ABSTRACT:
Harmonics in the AC output power of an inverter are sensed and are compared to corresponding references to produce a plurality of errors. These errors are used to produce a harmonic waveform which is in turn used in a triangular waveform PWM pulse generator to generate PWM pulses. The PWM pulses control the inverter so as to convert DC power into AC power and so as to reduce harmonics in the AC power.
