ZVS Analysis and Design for Half Bridge Bidirectional LLC-DCX Converter With Consideration of Nonlinear Capacitance and Different Load Under Synchronous Turn-On and Turn-Off Modulation

IEEE Transactions on Transportation Electrification, 2022
In the application of bidirectional LLC -DCX converter, synchronous turn-on and turn-off modulation can be adopted to simplify the control. In view of zero-voltage switching (ZVS) performance, conventionally, the magnetizing inductance is regarded as a ...

Minimum Backflow Power and ZVS Design for Dual-Active-Bridge DC–DC Converters

IEEE transactions on industrial electronics (1982. Print), 2022
Significant improvement in the power efficiency of dual-active-bridge dc–dc converters can be achieved by implementing zero voltage switching (ZVS) which is facilitated by a negative switch current at the switching instant. Such negative current, however,

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.

A novel ZVS direct coupling converter (DCC)

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
A novel DC-DC power converter with a ZVS topology is introduced. An amplitude modulated squarewave train is generated and the output can be controlled by the amplitude of this squarewave train. As energy is directly transferred to the output, it is known as a direct coupling converter (DCC).

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.
