| Abstract |
A new PAM-PWM inverter suitable for use with power MOSFETs is described. The output waveforms in the proposed PAM-PWM inverter are investigated both theoretically and experimentally. The line-to-line voltage waveform is composed of fundamental component and the sidebands of carrier frequency. The lower-order harmonics are not included in the output waveform. As each inverter arm does not operate during two-thirds 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. |
