ABSTRACT:
A method of controlling a pulse width modulation or PWM inverter apparatus that generates and controls AC output voltages with PWM control, comprises the steps of: generating a reference voltage vector for setting the AC output voltages; and changing timing of the generation of the AC output voltages during a predetermined period of time determined by a carrier signal at predetermined intervals determined by the carrier signal without changing the pulse widths of the AC output voltages determined by the PWM control so that a vector representing the averages of instantaneous amplitudes of the AC output voltages for a predetermined period of time agrees with the reference voltage vector, and so that the spectra of high-frequency components of each of the AC output voltages are spread out over a predetermined wide range of frequencies.
