external.blah(); //<-- what I end up with without realising.
So two questions really:
- What is "external" from "dhtml.js" (a file which does not exist to my knowledge) and why does Resharper have such an attachment to it?
- I did some googling but found nothing comprehensive: is it possible to stop Resharper 7 complaining about implicitly defined global variables on a case by case basis rather than altogether? Perhaps by defining them in a list somewhere within Resharper?

Remote control your electrical devices through your local network or internet. The circuit contains one output (Relay) and one input (isolated input). The whole project was built by using arduino nano platform and an ENC28J60 ethernet module. It can be used the W5100 ethernet module instead of ENC28J60, by replacing the UIPEthernet library to Ethernet library.
Moreover, the control is made from the Android application I wrote and it's available on Google Play (https://play.google.com/store/apps/details?id=com.serasidis.NetworkRelay).

Stephen Wylie , "Program two ATmegas w/an Arduino & AVRDUDE without re-cabling in between!"
Those of you who have programmed an Arduino through the Arduino or AVR Studio IDE may have noticed the utility that is really doing the work: AVRDUDE (AVR Downloader/UploaDEr). This is a powerful program that can facilitate programming new sketches on top of a bootloader, load a brand new bootloader or chip image, capture the current firmware programmed on the chip, and set fuse bits (which can render your chip unusable without special tools if you're not careful).

Today we'll explain how to exploit the potential of Arduino as a programmable logic controller, connecting it to appropriate interfaces for I/O.
The PLC (Programmable Logic Controller) has been and still is the basic component of the industrial automation world. The Industrial application made the PLC systems being very expensive, both to buy and repair, and also because of the highly specific skills requested to software designers to extract the maximum potentials from controllers. Arduino is a kind of universal programmable controller, although it is only the "core" and in any case it has been built for general applications; with a little of external hardware (essentially interfaces capable of transferring signals from sensors and to actuators, reducing the EMI which may damage the microcontroller) and an appropriate software may, however, become something very similar to a PLC.

Check out Cooking Hacks Arduino-based GPS tracker project for vehicles that could be extremely helpful to pinpoint the exact location of the vehicle in case it is stolen. The project uses a GPS+GPRS shield with an antenna to locate the coordinates of the vehicle. You need to call the device from your preset phone number, which will be verified by the SIM908 module on the tracker, and it will then send you an SMS with the GPS coordinates of its location.

I finally got round playing with my AVRASP v2.0 boards. The ones Sleepwalker3 mentioned. Thanks mate!
I bought three USBASP v2.0 on ebay for under £1.50 each. They each came with a short cable (5×2 sockets at each end). However, they do not come with the JP2 header soldered on. Solder it or you won't be able to re-flash the on-board ATmega8 chip. JP3 on the other hand has been deprecated. It may still have some use in your own projects. You decide!
Then download some software (this is for Windows): To use the USBASP programmer with the Arduino IDE, you will need to download the driver, latest firmware and WinAVR-20100110-install.

Sharon is a disgusting vile wart hog of a woman who is an utter liar . She's craves attention, and her daughter Kelly is as bad. Ozzy is just a drop kick idiot.
Aimee is prob the most normal Osbourne, and I have a lot of respect for her as she opted out of the osbourne show as she didn't want to be part of the immature madness.
Jack used to be as bad, but I have respect for him now as he cleaned up his act and is now a dedicated father.

Starting with a csharp-example and duly noting related SO questions ( Restart a windows services from C# and cannot restart a Service C#) and various other questions relating to restarting just one service, I'm wondering what the best method is for restarting a service with dependent services (e.g.
Message Queuing, on which
Message Queuing Triggers depends, or
IIS, on which
FTP Publishing and
World Wide Web Publishing depend). The mmc snap-in does this automagically, but the code doesn't seem to provide the same functionality (at least not as easily).
MSDN documentation for Stop says "If any services depend on this service for their operation, they will be stopped before this service is stopped. The DependentServices property contains the set of services that depend on this one," and
DependentServices returns an array of services. Assuming
StartService() and
StopService() follow the conventions outlined in the examples and such referenced above (except that they accept
ServiceControllers and
TimeSpans directly), I started with:
public static void RestartServiceWithDependents(ServiceController service, TimeSpan timeout)
ServiceController[] dependentServices = service.DependentServices;
RestartService(service, timeout); // will stop dependent services, see note below* about timeout...
foreach (ServiceController dependentService in dependentServices)
StartService(dependentService, timeout);
But what if the service dependencies are nested (recursive) or cyclical (if that's even possible...) - if
Service A is depended on by
Service B1 and
Service B2 and
Service C1 depends on
Service B1, it seems 'restarting'
Service A by this method would stop
Service C1 but wouldn't restart it...
To make this example picture clearer, I'll follow the model in the services mmc snap-in:
The following system components depend on [Service A]:
- Service B1
- Service C1
- Service B2
Is there a better way to go about this, or would it just have to recursively step into and stop each dependent service and then restart them all after it restarts the main service?
Additionally, will dependent but currently stopped services be listed under DependentServices? If so, wouldn't this restart them anyways? If so, should we control that as well? This just seems to get messier and messier...
*Note: I realize the
timeout isn't being applied completely correctly here (overall timeout could be many many times longer than expected), but for now that's not the issue I'm concerned about - if you want to fix it, fine, but don't just say 'timeout's broken...'
Update: After some preliminary testing, I've discovered (/confirmed) the following behaviors:
- Stopping a service (e.g.
Service A) that other services (e.g.
Service B1) depend on will stop the other services (including "nested" dependencies such as
Service C1)
DependentServicesdoes include dependent services in all states (Running, Stopped, etc.), and it also includes nested dependencies, i.e.
Service_A.DependentServiceswould contain
{Service B1, Service C1, Service B2}(in that order, as
C1depends on
- Starting a service that depends on others (e.g.
Service B1depends on
Service A) will also start the requisite services.
The code above can therefore be simplified (at least in part) to just stop the main service (which will stop all dependent services) and then restarting the most-dependent services (e.g.
Service C1 and
Service B2) (or just restarting "all" the dependent services - it will skip the ones already started), but that really just defers the starting of the main service momentarily until one of the dependencies complain about it, so that doesn't really help.
Looks for now like just restarting all the dependencies is the simplest way, but that ignores (for now) managing services that are already stopped and such...

Following the cancelation of several major game franchises in late January, THQ has gone on a game-announcement binge of sorts. After confirming Volition Studios was at work on sci-fi shooter Red Faction: Guerilla for the Xbox 360, PlayStation 3, and PC, THQ announced it would be taking a crack at the "untapped audience" on the Wii by jumping on the rhythm-game bandwagon with Band Mashups and crawling with platformer Deadly Creatures.
Today, THQ announced it would be contributing one more to the Wii and Nintendo DS's library, as well as the PC, with the help of Blue Fang Games. While the publisher has yet to reveal a title for the game, it is currently slated to arrive during THQ's fiscal year 2010, which runs from April 1, 2009 to March 31, 2010.
The first details on THQ and Blue Fang's collaboration are expected to arrive later this year. However, the title is likely to cater to the casual crowd, as Blue Fang is best known for its work on the Zoo Tycoon franchise of business management sims. Based in Waltham, Massachusetts, Blue Fang most recently partnered with THQ on the DS version of Zoo Tycoon, which set up shop on Nintendo's portable in 2005.

Using ion implant isolation, applicant has demonstrated a substantially planar quantum well photodetector free of exposed mesa side walls and having performance characteristics comparable with conventional mesa QWIPs. The planar photodetector presents a topography well suited for integration with other electronic components and the planar structure can be scaled to diameters much smaller than are typically useful in the conventional bonded devices.
1. A method for making a quantum well photodetector comprising the steps of:
providing a semiconductor substrate;
growing on the substrate a succession of layers forming an inner contact layer, a multiple quantum well stack, and an outer contact layer;
forming a mask over selected portions of the upper surface of the grown substrate;
isolating the active region under said mask by ion implantation;
removing the mask; and
forming ohmic contacts to the upper and lower contact layers.
2. The method of claim 1, wherein said substrate comprises gallium arsenide; said contact layers comprise n doped gallium arsenide; and said active region comprises a plurality of gallium arsenide quantum wells disposed between aluminum gallium arsenide barrier layers.
3. The method of claim 1, wherein said mask comprises a photoresist implantation mask.
4. The method of claim 1, wherein forming said ohmic contact to said lower layer comprises etching a via to said lower layer.
5. The method of claim 1, wherein forming said ohmic contact to said lower layer comprises ion implanting a conductive path to said lower layer.
This is a division of application Ser. No. 07/860,853 filed Mar. 31, 1992, now U.S. Pat. No. 5,223,704.
This invention relates to quantum well photodetectors and, in particular, to such a photodetector which is essentially planar in surface topography.
Photodetectors are of interest in a wide variety of fields including optical communications, image sensing and instrumentation. Because of their low dark current and high responsivity, quantum well infrared photodetectors (QWIPs) offer considerable promise as high speed infrared photodetectors.
A particularly advantageous QWIP structure is disclosed in U.S. Pat. No. 4,894,526 to C. G. Bethea et al entitled Infrared Radiation Detector. In one embodiment the QWIP comprises a plurality of GaAs/AlGaAs quantum wells having a single bound state for electrons. Incident infrared radiation excites electrons from their bound state into the conduction band where they contribute to collected current.
A limitation of prior art QWIPs is that the quantum well regions are typically fabricated as mesa structures arising three or more micrometers from the underlying n+ semiconductor contact layer. The mesas present an extreme topography which is not readily compatible with integration of other electronic devices on the same substrate. Moreover the side walls expose the active area of the device to the degrading effects of contamination and radiation. Because the mesa topography is not suitable for integration, the conventional QWIPs must be fabricated in dimensions sufficiently large to be aligned and bonded to other substrates containing integrated circuits. Although smaller mesas would be desirable, this bonding requirement limits the minimum mesa diameter to about 30 micrometers. Accordingly, there is a need for a QWIP structure which eliminates mesa topography.
Applicant has demonstrated that ion implant isolation permits fabrication of a substantially planar quantum well photodetector free of exposed mesa side walls and having performance characteristics comparable with conventional mesa QWIPs. The planar photodetector presents a topography well suited for integration with other electronic components, and the planar structure can be scaled to dimensions smaller than conventional bonded devices.
The advantages, nature and various additional features of the invention will appear more fully upon consideration of the illustrative embodiments now to be described in detail in connection with the accompanying drawings. In the drawings:
FIG. 1 is a schematic cross section of a conventional mesa quantum well infrared photodetector;
FIG. 2 is a schematic cross section of a planar quantum well photodetector in accordance with the invention;
FIG. 3 is a graphical illustration of the current versus voltage curve of the device of FIG. 2; and
FIGS. 4 and 5 are graphical illustrations comparing performance characteristics of the devices of FIGS. 1 and 2.
FIGS. 6-7 are graphical illustrations comparing performance characteristics of different size devices of the type shown in FIG. 2.
It is to be understood that these drawings are for purposes of illustrating the concepts of the invention and, except for graphical illustrations, are not to scale.
Referring to the drawings, FIG. 1 is a schematic cross section of a conventional mesa quantum well infrared photodetector useful in understanding the limitations of the prior art. In essence the conventional QWIP comprises a plurality of quantum wells referred to as a multiple quantum well stack 10 in the form of a mesa rising from an n+ surface 11 of a gallium arsenide substrate 12. A second n+ region 14 is disposed on the upper surface of the mesa to act as a contact layer, and upper and lower ohmic contacts 15 and 16, respectively, are formed on the n+ layers by methods well known in the art. Examples of such devices are described in the above-cited Bethea et al '526 patent.
Limitations of this conventional structure may be seen in FIG. 1. The mesa, which is typically about four micrometers in height above surface 11 has large, exposed side walls 13. The extreme topography presented by the mesa is not readily compatible with integration of other components on the same chip. In addition the exposed sidewalls expose the active area of the device to the degrading effects of contamination and radiation.
FIG. 2 is a schematic section of a QWIP in accordance with the invention which avoids extreme mesa topography, is free of exposed side walls and presents a geometry compatible with integration of other components. In essence, the QWIP of FIG. 2 comprises a multiple quantum well stack 20 grown from an n+ surface 21 of a gallium arsenide substrate 22. Instead of mesa isolation, however, the stack 20 is isolated by ion implantation in the neighboring regions 23. A second n+ region 24 is disposed on the top of the multiquantum well stack to act as a contact layer. A conductive path 27 is provided to surface 21 by etching a via or implanting through region 23, and metal contacts 25 and 26 are made.
The fabrication and structure of the invention can be understood in greater detail by consideration of the following specific example. The exemplary structure can be conveniently fabricated by using molecular beam epitaxy (MBE) to grow the layers for the contacts and the multiple quantum well stack on a semiconductor substrate.
The first step in the fabrication process is to provide a semiconductor substrate such as gallium arsenide and to form a contact layer 21, such as a one micrometer thick layer of n+ doped gallium arsenide.
The next step is to grow the multiple quantum well stack 20 as by growing 50 periods of 40 angstrom GaAs quantum wells (n-doped to a concentration 1�1018 cm-3) and 500 angstrom Al0.28 Ga0.72 As barriers.
The top contact layer 24 grown on the top of stack 20 can be 0.5 micrometers of n+ doped gallium arsenide.
After the requisite layers are grown, the active quantum well region is masked. Here the quantum well region is defined by photolithographically forming circular dots of thick photoresist (about 5 micrometers thickness) over the upper surface and using the dots as masks for ion implantation isolation. A plurality of different size devices were made by using different diameter dots of 15, 25, 50, 100 and 200 micrometers. Specifically, the stack 20 is isolated by subjecting the neighboring regions 23 to multiple F+ (alternatively O+) and H+ implants with energies up to 200 and 350 KeV, and doses up to 8�1012 and 1�1015 cm-2, respectively.
In the final steps the photoresist is stripped, and the stripped devices are annealed at 500� C. for 5 min. in order to maximize the resistivity of the implanted regions. Conductive paths 27 are made to the lower n+ contact layer 21, either through vias or implanted regions, and ohmic metal contacts 25 and 26 provide contact to layers 21 and 24 in accordance with techniques well known in the art.
The resulting QWIPs were then tested. A 200 micron implanted QWIP was tested in comparison with a mesa isolated QWIP of the same size and layer structure. The current-voltage curves for both QWIPs were measured and found to identical within experimental error. FIG. 3 shows (for either device) the dark current curves measured at T=77K and the window photocurrent curves measured at T=20K. Since the dark current is extremely sensitive to the quality of the aluminum gallium arsenide barriers, FIG. 3 demonstrates that the ion implantation and anneal process does not produce any substantial concentration of defects or traps in the barrier layers.
The two devices were then provided with 45� facets polished on the substrates to permit optical coupling, and the responsivities of the devices were measured as a function of wavelength. The results are plotted in FIG. 4 with the dashed curve for the mesa QWIP and the solid curve for the planar QWIP. As can be seen, the normalized responsivity spectra are nearly the same, showing no measurable degradation of device performance due to ion implantation.
The next test was to measure current noise as a function of bias voltage at T=77K. The results, shown in FIG. 5, show that the mesa and planar devices perform the same. Thus with no loss in performance, QWIPs can be made in planar form suitable for monolithic integration with other devices such as signal processing electronics.
Next the different diameter implanted devices were tested in comparison with one another to determine whether the process can be used to make smaller devices of comparable quality. FIG. 6 shows the dark current measured at �0.52 and �2.4 V for implanted devices of different diameter. As can be seen, there is an excellent linear fit of the square root of dark current to device diameter. The fit demonstrates that the implantation perimeter contributes little to the thermionic current. The fact that the linear fitted lines intersect the x-axis at about 11 micrometers suggests that about 5.5 micrometers of each device radially within the perimeter is electrically inactive due to the combination of implantation and rapid thermal annealing.
FIG. 7 shows the window photocurrent measured at �2.4 V for several different diameter devices, and FIG. 8 shows the ratio of window current to the dark current. The constant ratios over a wide range of device size demonstrates the scalability of the technology. In addition current noise scaled with device size. Thus, the detectivity of the implanted devices is comparable to the detectivity of mesa devices and independent of device size, permitting the fabrication of devices comparable in quality to conventional mesa devices but smaller in size and compatible with integrated circuit fabrication.
It is to be understood that the above-described embodiments are illustrative of only some of the many possible specific embodiments which can represent applications of the principles of the invention. For example, while the invention has been described in the context of a preferred gallium arsenide materials system, other materials systems such as indium phosphide and gallium antimonide those skilled in the art without departing from the spirit and scope of the invention.

In this bold new addition to the Provocations
The Madness of Modern ParentingParenting in the modern world is an overwhelming concept. It seems to divide everyone from psychologists and politicians to scientists and salesmen, leaving the parents themselves with a terrible headache as a result. How can anyone live up to such expansive and conflicting expectations? As Zoe Williams explores, the madness begins before the baby has even arrived: hysteria is rife surrounding

While there has been no reported case of overdosage, should it occur, symptomatic supportive measures should be taken.
Clofibrate is contraindicated in pregnant women. While teratogenic studies have not demonstrated any effect attributable to clofibrate, it is known that serum of the rabbit fetus accumulates a higher concentration of clofibrate than that found in maternal serum, and it is possible that the fetus may not have developed the enzyme system required for the excretion of clofibrate.
It is contraindicated in patients with clinically significant hepatic or renal dysfunction. Rhabdomyolysis and severe hyperkalemia have been reported in association with pre-existing renal insufficiency.
It is contraindicated in patients with primary biliary cirrhosis, since it may raise the already elevated cholesterol in these cases.

Say I have a MySQL table:
CREATE TABLE tweets (
tweet_id INT NOT NULL AUTO_INCREMENT,
author_id INT NOT NULL,
text CHAR(140) NOT NULL,
PRIMARY KEY (tweet_id)
PARTITION BY HASH(tweet_id)
All is good. The table lives on a single server - Server1. But eventually I may want to scale out. So I'd want to shard the table and move 6 of the 12 partitions onto a new server - Server2.
I'd want:
- Server1 to contain odd-numbered tweets: partitions 1, 3, 5, 7, 9, 11
- Server2 to contain even-numbered tweets: partitions 2, 4, 6, 8, 10, 0
1) What is the best way to move those partitions from Server1 to Server2? I need to make sure the values of the auto-increment tweet_id's remain unchanged during the migration.
2) Now that I have 2 servers, how do I make sure the auto-increment tweet_id's generated by the 2 servers don't have the same value? I'd also need to make sure the tweet_id on each partition stays consistent, i.e. on Partition k every tweet_id's modulo 12 equals to k.
3) Ideally I'd like to continue this scale out process. So later on I'd want to add a 3rd server - Server3. I'd want to re-balance the partitions so that there're 4 partitions on each server. Again how do I make sure the auto-increment tweet_id's generated by the 3 servers are distinct and that the modulo 12 of tweet_id's stay consistent within each partition?

I am concerned that the city is not regulating enough public parking in these complexes. I am not talking about guest parking, which is required but public parking. The streets are already filled up with people parking on this side of Central Expy, so that they can have free parking instead of using the paid parking in the city lots across the way.
The traffic on Moffett is already terrible. Closing the ramp is going to increase traffic. What is city council thinking?
Don't miss out on the discussion!

In a power converter, the duty cycle of a primary winding circuit causes near continuous flow of power through the primary and secondary winding circuits during normal operation. By providing no regulation during normal operation, a very efficient circuit is obtained with a synchronous rectifier in the secondary operating at all times. However, during certain conditions such as start up or a short-circuit, the duty cycle of the primary may be reduced to cause freewheeling periods. A normally non-regulating isolation stage may be followed by plural non-isolating regulation stages. To simplify the gate drive, the synchronous rectifiers may be allowed to turn off for a portion of the cycle when the duty cycle is reduced. A filter inductance of the secondary winding circuit is sufficient to minimize ripple during normal operation, but allows large ripple when the duty cycle is reduced. By accepting large ripple during other than normal operation, a smaller filter inductance can be used.
1. A power converter system comprising:
a normally non-regulating isolation stage comprising:
a primary winding circuit;
a secondary winding circuit coupled to the primary winding circuit, the secondary winding circuit comprising a secondary transformer winding in series with a controlled rectifier having a parallel uncontrolled rectifier; and
a control circuit which controls duty cycle of the primary winding circuit, the duty cycle causing substantially uninterrupted flow of power through the primary and secondary winding circuits during normal operation; and
a plurality of non-isolating regulation stages, each receiving the output of the isolation stage and regulating a regulation stage output.

No. 5,999,417, which claims the benefit of U.S. Provisional Application 60/036,245 filed Jan. 24, 1997. The entire teachings of the above applications are incorporated herein by reference.
This invention pertains to switching power converters. A specific example of a power converter is a DC-DC power supply that draws 100 watts of power from a 48 volt DC source and converts it to a 5 volt DC output to drive logic circuitry. The nominal values and ranges of the input and output voltages, as well as the maximum power handling capability of the converter, depend on the application.
It is common today for switching power supplies to have a switching frequency of 100 kHz or higher. Such a high switching frequency permits the capacitors, inductors, and transformers in the converter to be physically small. The reduction in the overall volume of the converter that results is desirable to the users of such supplies.
Another important attribute of a power supply is its efficiency. The higher the efficiency, the less heat that is dissipated within the supply, and the less design effort, volume, weight, and cost that must be devoted to remove this heat. A higher efficiency is therefore also desirable to the users of these supplies.
A significant fraction of the energy dissipated in a power supply is due to the on-state (or conduction) loss of the diodes used, particularly if the load and/or source voltages are low (e.g. 3.3, 5, or 12 volts). In order to reduce this conduction loss, the diodes are sometimes replaced with transistors whose on-state voltages are much smaller. These transistors, called synchronous rectifiers, are typically power MOSFETs for converters switching in the 100 kHz and higher range.
The use of transistors as synchronous rectifiers in high switching frequency converters presents several technical challenges. One is the need to provide properly timed drives to the control terminals of these transistors. This task is made more complicated when the converter provides electrical isolation between its input and output because the synchronous rectifier drives are then isolated from the drives of the main, primary side transistors. Another challenge is the need to minimize losses during the switch transitions of the synchronous rectifiers. An important portion of these switching losses is due to the need to charge and discharge the parasitic capacitances of the transistors, the parasitic inductances of interconnections, and the leakage inductance of transformer windings.
In certain embodiments of the invention, a power converter system comprises a normally non-regulating isolation stage and a plurality of non-isolating regulation stages, each receiving the output of the isolation stage and regulating a regulation stage output. The non-regulating isolation stage may comprise a primary winding circuit and a secondary winding circuit coupled to the primary winding circuit. The secondary winding circuit comprises a secondary transformer winding in series with a controlled rectifier having a parallel uncontrolled rectifier. A control circuit controls duty cycle of the primary winding circuit, the duty cycle causing substantially uninterrupted control of power through the primary and secondary winding circuits during normal operation.
The duty cycle of the primary winding circuit may be reduced to cause freewheeling periods in other than normal operation. Duty cycle might be reduced during the startup or to limit current and may be a function of sensed current.
The primary winding circuit may include a single primary winding, and the secondary winding circuit may include plural secondary windings coupled to the single primary winding. The primary winding may be in a full bridge circuit having a capacitor in series with the primary winding. In one implementation of the full bridge circuit, during freewheeling, only two top FETs or two bottom FETs are turned off.
A control signal of the controlled rectifier may be derived from a waveform of the secondary winding circuit. The secondary winding circuit may include a filter inductor and have a capacitor coupled across its output.
The isolation stage may be a step down stage. For example, it may provide an output of about 12 volts from a DC power source that provides a voltage varying over the range of 36-75 volts. The regulation stages may be down converters to provide outputs of voltage levels to drive logic circuitry. A regulation stage output may, for example, be 5 volts or less, such as 3.3 volts.
The foregoing and other objects, features and advantages of the invention will be apparent from the following more particular description of preferred embodiments of the invention, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention.
A description of preferred embodiments of the invention follows.
During the second half of the cycle, MOSFETs 102 and 104 are turned on while MOSFETs 101 and 103 are left off, and the voltage VB is applied negatively across the transformer's primary winding. This negative polarity causes MOSFET 106 to be turned on, MOSFET 105 to be turned off, and power to flow into the primary winding and out of the second secondary winding 109 to the output across capacitor 110.
The secondary windings are not tightly coupled to each other, as indicated with the parasitic inductances 113 and 114, to achieve the advantages discussed in the '417 patent. A similar setup was shown in the topology of
Care must be taken in this isolation stage topology to insure that the magnetizing inductance of the transformer does not saturate. One way to do this is to place a large capacitor 215 in series with the primary winding, as shown in
The filters at the output of the isolation stages in the '417 patent are composed of one or more capacitive and inductive elements. When the isolation stage is voltage-fed, it may be desirable to have the output filter begin with an inductor 316, as shown in
Under variable duty cycle control, the percentage of the overall cycle (the duty cycle) that MOSFETs 101 and 103 (or MOSFETs 102 and 104) conduct is reduced from the 50% value described above. For the remaining, freewheeling fraction of the half-cycle, either all of the primary-side MOSFETs are turned off, or at least the two top MOSFETs 101 and 104 or the two bottom MOSFETs 102 and 103 are turned off. During the freewheeling part of the cycle, both diodes 111 and 112 conduct the current flowing through inductor 316, and the voltage across the transformer windings is approximately zero. As is well know, this additional portion of the cycle permits the output voltage to be less than VB divided by the transformer's turns-ratio. How much less depends on the duty cycle. Since during normal operation the isolation stage is operated at a fixed duty cycle in which power is always flowing from input to output (except during the brief switch transitions), the value of inductor 316 can be relatively small to achieve an acceptable output ripple. This reduces the size, cost, and power dissipation of this inductor compared to what it might have been. During those times when the isolation stage is operated under a variable duty cycle, the ripple in the inductor current may then become large, but the larger output voltage ripple that results can usually be tolerated for start-up and short-circuit conditions.
As mentioned above, during the freewheeling part of the cycle the diodes are carrying the inductor current. This is because the gate drive scheme shown in
If the output voltage is high, then it may be desirable to use a capacitive divider technique described in the '417 patent to reduce the voltages applied to the gates of the MOSFET synchronous rectifiers below that of the voltages appearing at Nodes A and B.
In addition, since the converter of
Note in this schematic that the IC labeled U100 is a pulse width modulator (PWM) control chip that is normally operated such that the gate drive signals that pass through gate drivers U101 and U105 give the fixed duty cycle operation of the full-bridge described above. If the current sensing amplifier U104-A senses that the current flowing on the primary side of the circuit exceeds a threshold value, it commands the PWM control chip to reduce its duty cycle by an amount determined by how large the current gets above the threshold value. This provides a current limiting scheme for the product that protects against a short-circuit condition.
Note also that comparator U106-A senses the duty cycle output of the PWM control chip, and compares it to a threshold. If the duty cycle falls below this threshold value, the output of the comparator causes the PWM control IC to shut down. The circuitry around this comparator, including transistors Q111 and Q114, provides a latching mechanism such that the PWM control IC remains off once this condition is observed.
As described in the '417 patent and illustrated in
The DC power source to the full bridge primary circuit may provide a voltage that varies over the range of 36-75 volts. The output of the isolation stage may be 12 volts, and the regulation stage output may be 5 volts or less. In particular, the regulation stage output may be 3.3 volts. Typically, the regulation stage output is of a voltage level to drive logic circuitry.
Because the isolation stage uses synchronous rectifiers, it is possible for the current to flow from the output back to the input if, for a given input voltage and duty cycle, the output voltage is too high. This condition might, for example, occur during start-up where the duty cycle is slowly raised from its minimum value to its maximum value, but the output capacitor is already pre-charged to a high voltage, perhaps because it had not fully discharged from a previous on-state condition. It might also occur when the input voltage suddenly decreases while the output voltage remains high due to the capacitors connected to this node.
The negative current that results could cause destructive behavior in the converter or in the system if it is not kept small enough.
One way to avoid this condition is to turn off either just the top two primary-side MOSFETs 101 and 104, or just the bottom two primary-side MOSFETs 102 and 103, during the freewheeling period, as described above. By leaving the other two primary-side MOSFETs on, the voltage across the primary and secondary windings of the transformer is guaranteed to be essentially zero during the freewheeling period. Given the gate drive scheme shown in
With the controlled rectifiers off, negative current cannot flow during the freewheeling period. Negative current can flow during the non-freewheeling part of the cycle, but since it must always start at zero, its value is limited to the ripple that the inductor permits, which is typically small enough to not cause a problem. This negative current will be reset to zero at the start of each freewheeling period, either by providing a clamp circuit, as shown in
To limit the negative current, the isolation stage could operate in a reduced duty-cycle mode. While the control circuit is typically designed to achieve this mode during start-up and shutdown of the isolation stage, it is not the normal mode of operation. If, during normal operation, the input voltage drops suddenly, a large negative current can flow because there are no freewheeling periods.
To avoid this condition, the current flowing through the converter can be sensed, either by sensing the load current directly, or by sensing a signal indicative of the load current. When the load current falls below some threshold, the duty cycle of the isolation stage can be reduced from its maximum value to provide freewheeling periods. Given the drive scheme for the primary-side MOSFETs outlined above, the negative current will then be kept small since the controlled rectifiers will be turned off for a portion of the cycle.
While this invention has been particularly shown and described with references to preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention encompassed by the appended claims. For example, whereas the Figures show the secondary side rectification circuit arranged in a center tapped configuration with two secondary windings and two synchronous rectifiers, as is well known it could be a full wave rectification configuration. One could use a full-bridge rectification circuit in which there is only one secondary winding and four synchronous rectifiers. Such a circuit reduces voltage stress on the synchronous rectifiers when they are off by a factor of two during normal operation of the converter.
