ABSTRACT:
A PWM inverter with a PWM pulse output. The PWM pulse signal is output upon magnitude comparison of phase voltage commands with a carrier wave of a triangular or a saw-tooth waveform. A maximum phase whose absolute value is a maximum among absolute values of phases of the phase voltage commands is selected. In a case where the phase voltage commands of the maximum phase are larger than a maximum value of the carrier wave. A difference obtained from a first subtraction of the maximum value of the carrier wave from phase voltage commands of the maximum phase is set as a first differential. The first differential is subtracted from the phase voltage commands of the respective phases in a second subtraction. The first and second subtraction results are set as phase output voltage commands of the respective phases.
