IEEE Transactions on Industrial Electronics, 2008 A full zero voltage switching (ZVS) range transient current buildup half-bridge converter is proposed. The proposed converter controls the secondary synchronous switches to build up the current for the ZVS operation. In addition, the blocking capacitor in the secondary side of the transformer is used to make the different current buildups and different

Analysis and Derivations for a Family ZVS Converter Based on a New Active Clamp ZVS Cell
IEEE Transactions on Industrial Electronics, 2008A 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.

A ZVS Grid-Connected Full-Bridge Inverter With a Novel ZVS SPWM Scheme
IEEE Transactions on Power Electronics, 2016A 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, 2008A 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, 2016Aiming 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{

Implementation of a new ZVS DC/DC converter to extend ZVS range
TENCON 2015 - 2015 IEEE Region 10 Conference, 2015A novel zero-voltage switching (ZVS) converter is studied in this paper. The proposed converter consists a three-level converter and a LLC converter with same active switches to have wide ZVS load range and to reduce conduction losses at freewheeling interval. Series resonant converter with fixed switching frequency is adopted to improve ZVS load range
