I am build a full-bridger single phase inverter that uses PWM to switch the transistors at 18kHz. I am using the following equation to come up with an LC filter:
fc = 1/(2*pi*sqrt(LC))
Does anyone know a range of cut-off frequencies that would eliminate most of the harmonics and still keep the 60 HZ fundamental frequency with minimal attenuation?
