Abstract
A new PWM inverter suitable for use of power MOSFETs is described. The output waveforms in the proposed PWM inverter are investigated both theoretically and experimentally. A modulating signal for the three-phase PWM inverter is obtained by superposing a rectangular wave on the specific trapezoidal wave. This modified signal lends itself to a simple three-phase construction. The output PWM waveform for the new modulating signal does not include the fifth harmonic component and an amplitude of fundamental component is increased by about 20 percent more than that of a conventional PWM inverter. As each inverter arm does not operate during two-third period, the heat generated in the devices are reduced. That is, the size of the inverter system is minimized because of the reduction in the heat dissipating equipment.
