Abstract

This paper presents a zero-voltage-switching (ZVS) pulse-width-modulated (PWM) single-phase inverter and the establishment of a V-connected three-phase inverter using two such single-phase modules. All main switches in the ZVS-PWM inverter operate at ZVS turn-on. The auxiliary switches operate at zero-current-switching (ZCS) turn-off. Since commutations of the main power devices occur with low losses, higher efficiency is achieved. Moreover, two single-phase ZVS-PWM inverter modules are then connected to form a V-connected soft-switching three-phase inverter. Some experimental results are presented for verification.
