Abstract

The inverter has an improved output filter (12) including a low pass filter (38, 39) for providing a sine wave output in response to a pulse width modulated waveform and a notch filter (40) coupled to the low pass filter and tuned to the frequency of the pulse width modulated waveform to eliminate that frequency from the sine wave output. The inverter also includes a series resonant circuit (54) coupled across the DC power supply (20) of the inverter and tuned to two times the frequency of the sine wave output to provide a low impedance path for AC current flowing to the power supply.
