Grounding my Capacitor Banks
Your circuit designs don't make sense, and won't work.

Your first circuit won't work because there is nothing in place to discharge the capacitors. There will be a current through the coil while the capacitors charge, then nothing once they've charged.

Your second circuit won't work for several reasons:


You cannot charge a capacitor to a higher voltage than it is being supplied with. If the voltage present across your bridge rectifier were 2.5V, the capacitor bank will charge to 2.5V, and no higher.
The "smoothing supercapacitors" present the same problem as the capacitor bank in the first circuit. They will act as an open circuit once charged.
If the primary capacitor bank actually charged, discharging it would lead to a flyback current that would probably blow out the bridge rectifier and protection diodes.




As others have noted, you are in way over your head here. The voltages and currents you're describing are extremely hazardous. You are at serious risk of injuring or killing yourself or someone else. Step back and get some more experience in basic electronics before you attempt to proceed.
