A novel approach for achieving ZVS operation in class-D ZVS inverter

2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS), 2017
This paper presents a novel approach to fulfill the zero-current switching (ZVS) operation of the class-D ZVS inverter by utilizing the anti-parallel diode of transistor actively which enables a switching-timing allowance to be produced. The switching-timing allowance of the class-D ZVS inverter at any duty ratio is derived.

A ZVS-PWM inverter using a simple ZVS-PWM auxiliary commutation pole

2011 6th IEEE Conference on Industrial Electronics and Applications, 2011
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-
