Zero-Voltage Switching Operation of Transformer Class-E Inverter at Any Coupling Coefficient

IEEE transactions on industrial electronics (1982. Print), 2019
This paper presents a complete design methodology of a Class-E inverter with a loosely coupled transformer under zero-voltage switching conditions. At a selected maximum coupling coefficient, the inverter satisfies both zero-voltage switching (ZVS) and ...

Voltage fed zero-voltage zero-current switching PWM DC-DC converter

2008 13th International Power Electronics and Motion Control Conference, 2008
A new zero-voltage zero-current switching full-bridge phase-shifted PWM converter with controlled output rectifier is presented in this paper. IGBT switches are used in the high-frequency inverter of the DC-DC converter. Zero-voltage turn-on and zero-current turn-off for all power switches of the inverter is achieved for full load range from no-load to

Switching losses of IGBTs under zero-voltage and zero-current switching

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
Turn-off switching losses of punch-through (PT) and nonpunch-through (NPT) IGBTs under hard switching (HS) and zero-voltage switching (ZVS) are presented and evaluated at 25/spl deg/C, 75/spl deg/C and 125/spl deg/C. A comparison between PT and NPT devices based on their internal device characteristics is given for HS and ZVS.

A zero voltage switching switched capacitor voltage doubler

2012 IEEE International Symposium on Industrial Electronics, 2012
Switched capacitor converter has advantages such as no magnetic components, compact size. With the target to reach high power, high switching frequency is preferred. In order to achieve high efficiency, soft switching becomes vital. This paper proposes a soft switched voltage doubler and its PWM scheme, with which, all switches in the converter turns ...

Zero-voltage-switching multi-resonant three-level converters

2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004
This paper proposes a family of zero-voltage-switching multiresonant three-level converters (ZVS-MR-TLCs), which are derived by adding a ZVS-MR multiresonant network to the TLCs. The arrangement of a multiresonant network results in the absorption of all the major parasitic components in the resonant circuit, including the switch output capacitor ...

Multiple-Phase-Shift Control for a Dual Active Bridge to Secure Zero-Voltage Switching and Enhance Light-Load Performance

IEEE transactions on power electronics, 2018
An ac/dc + dual active bridge (DAB) circuit was found as one solution for the high-efficiency and high-power-density electric vehicle charger. One control option is to let the ac/dc part only convert the grid voltage to a double-line-frequency folded ...

A new zero voltage and zero current power switching technique

20th Annual IEEE Power Electronics Specialists Conference, 1992
An outline is presented of work done by the authors on a novel converter topology where the power switching occurs at both zero current and zero voltage, giving it some major advantage over the present state of the art. A description is given of the application of this topology to both high and low-output-voltage converters.

A Zero Voltage Switching Topology for Non-Inverting Buck–Boost Converter

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2019
This brief summarizes soft-switching methods for the non-inverting buck-boost converter (NIBBC). Then a new zero voltage switching (ZVS) NIBBC is proposed. This new NIBBC employs a triple coupled inductor, two resonant inductors, and two auxiliary diodes.
