Inverter Output Signal (Filter Input Signal) becomes distorted when LC Low pass filter is connected. Need Help please
Thanks Tony. It turned out that my input signal was distorted because of reflections back from my filter creating a standing wave as seen on my oscilloscope. I calculated the input impedance of my LC Filter which was Zin=Zc+Zl which it then turn out to be capacitive at my fundamental frequency. I then built a impedance matching circuit at the output of my inverter H-bridge and this got rid of my input signal reflections!
