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.

Implementation of a new ZVS DC/DC converter to extend ZVS range

TENCON 2015 - 2015 IEEE Region 10 Conference, 2015
A 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

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.

An Improved ZVS PWM Three-Level Converter

IEEE Transactions on Industrial Electronics, 2004
This paper proposes an improved zero-voltage-switching pulse-width-modulation three-level converter (ZVS PWM TLC), which is improved from the original ZVS PWM TLC just by exchanging the position of the resonant inductor and the transformer, such that the transformer is connected with the lagging switches.

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{
