A new zero-voltage-switching (ZVS) pulsewidth-modulated (PWM) single-phase inverter using. a simple ZVS-PWM commutation cell is presented in this paper. Except for the auxiliary switches, all switching devices in the ZVS-PWM single-phase inverter operate at ZVS turn on and turn off. The auxiliary switches operate at zero-current-switching turned-on and turned-off. Besides operating at constant frequency, the proposed inverter has no overvoltage across the switches 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 1 kW and operated at 40 kHz, are. provided in this paper to verify the performance.
