Abstract

A new zero-voltage-switching (ZVS) pulsewidth-modulated (PWM) single-phase inverter using a simple ZVS-PWM auxiliary commutation pole is presented in this paper. Except for the auxiliary switches, all active and passive semiconductor devices in the ZVS-PWM single-phase inverter operate at ZVS turn on and turn off. The auxiliary switches operate at zero-current-switching (ZCS) turned-on and turned-off. Besides operating at constant frequency, the proposed inverter has no additional voltage and current stresses on the main switch compared to the hard switching inverter counterpart. Auxiliary components rated at very small current are used. The principle of operation, theoretical analysis, and experimental results of the new ZVS-PWM single-phase inverter, rated 600W and operated at 40 kHz, are provided in this paper to verify the performance.
