A ZVS Grid-Connected Full-Bridge Inverter With a Novel ZVS SPWM Scheme

IEEE Transactions on Power Electronics, 2016
A zero-voltage switching (ZVS) grid-connected full-bridge inverter and its modulation schemes are investigated. A novel sinusoidal pulse width modulation scheme for the ZVS full-bridge inverter (ZVS SPWM) is proposed in this paper. The ZVS SPWM is evolved from the double-frequency SPWM by adding gate drive to the auxiliary switch.

A ZVS-PWM Single-Phase Inverter Using a Simple ZVS-PWM Commutation Cell

IEEE Transactions on Industrial Electronics, 2008
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.

ZVS of Power MOSFETs Revisited

IEEE Transactions on Power Electronics, 2016
Aiming for converters with high efficiency and high power density demands converter topologies with zero-voltage switching (ZVS) capabilities. This letter shows that in order to determine whether ZVS is provided at a given operating point, the stored charge within the mosfet s has to be considered and the condition $L I^2 \geq 2Q_\text{oss} V_\text{

Analysis and Derivations for a Family ZVS Converter Based on a New Active Clamp ZVS Cell

IEEE Transactions on Industrial Electronics, 2008
A new zero voltage switching (ZVS) cell is proposed based on the active clamping technique. With a small clamping diode in the cell, the voltage ringing caused by the auxiliary inductor and the parasitic capacitance of the diode is eliminated, and therefore, the circulating loss is minimized.
