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{

ZVS Boost Converter with Wide ZVS Range

2011
A zero-voltage-switching (ZVS) boost converter with wide ZVS range is proposed in this paper. A ripple-free cell is added to a conventional two-switch boost converter. The ripple-free cell provides a ripple-free input current and ZVS operation of two switches. Due to the ZVS feature, the switching loss is significantly reduced.

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.

A Novel ZVS-PWM Single-Phase Inverter Using a Voltage Clamp ZVS Boost DC Link

2007 2nd IEEE Conference on Industrial Electronics and Applications, 2007
A novel zero-voltage-switching pulse-width-modulation (ZVS-PWM) single-phase inverter using a voltage clamp ZVS boost dc link is proposed in this paper. The proposed voltage clamp ZVS boost dc link not only provides the switches in the section of conventional PWM buck inverter operate at ZVS, but it has a boost input voltage function and the switches ...
