<p>A control for an inverter having a switch (Q1-Q6) which is operated in accordance with a PMW waveform having spaced rising and falling edges includes circuitry (66) which detects the magnitude (76) and polarity (78) of a DC component in the AC output power produced by the inverter and an adder (64)/substractor which adjusts at least one of a rising and falling edge of the waveform to reduce the magnitude of the DC component.</p> |
