Abstract

In this study, a new sinusoidal PWM inverter suitable for use with power MOSFETs is described. The output waveforms in the proposed OWM inverter are investigated both theoretically and experimentally. A modulating signal for the three-phase PWM inverter is obtained by adding 3nth harmonics to the conventional three-phase sine wave. By using the new modulating signal, the amplitude of the fundamental component is increased about 15 percent more than that of a conventional sine wave inverter and the commutation number of the inverter is decreased to two-thirds of a conventional one.
