A Novel ZVS-PWM Single-Phase Inverter Using a New Simple ZVS-PWM Commutation Cell

2007 2nd IEEE Conference on Industrial Electronics and Applications, 2007
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 active and passive semiconductor devices in the ZVS-PWM single-phase inverter operate at ZVS turn on and turn off.

Double-Ended ZVS Half-Bridge Zeta Converter

2007 IEEE Power Electronics Specialists Conference, 2007
A new double-ended type zero-voltage switching (ZVS) half-bridge zeta (HBZ) converter employing a double-ended rectifier (DER) is proposed. The proposed DER for the HBZ converter provides a bidirectional powering path in the rectifier. As a result, the improved voltage waveform of the rectifier reduces the output filter size and voltage stresses on ...

Analysis and Derivations for a Family ZVS Converter Based on a New Active Clamp ZVS Cell

IEEE Transactions on Industrial Electronics, 2008
A 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.

Die Rolle der ZVS

1997
Als Hurde, als burokratisches Hindernis auf dem Weg zum Studienplatz wird sie haufig angesehen, die Zentralstelle sr die Vergabe von Studienplatzen in Dortmund, besser bekannt unter dem Kurzel ZVS. Bezogen auf die wirtschaftswissenschaftlichen Studienmoglichkeiten haben der Ausbau von Studienplatzen und die rucklaufige Nachfrage allerdings diese Hurde,

Active Magnetizing Current Splitting ZVS Modulation of a 7 kV/400 V DC Transformer

IEEE transactions on power electronics, 2020
The LLC series resonant converter (SRC) is one of the most popular galvanically isolated dc–dc converters since it provides zero voltage switching (ZVS), reduces rms currents, and tightly couples the input and output voltages, when it is operated at (or ...

Single phase ZVS PWM NPC inverter

XI Brazilian Power Electronics Conference, 2011
This paper presents a zero-voltage, pulse width modulated, NPC inverter, with active voltage clamping using only two auxiliary switches. The structure is particularly simple and robust. It is very attractive for high-power applications, single or multiple phases, due to neutral point accessible at the NPC topology.

Gate driver circuit for ZVS mode

2016 XXV International Scientific Conference Electronics (ET), 2016
This paper considers problems related with the switching losses in the power supply units, based on a high frequency inverters. Different ways to overcome some of the problems are discussed. A ZVS gate driver circuit for transistors in resonant DC/DC converter is proposed. The influence of the snubber capacitors value is studied.

A Control Strategy for Efficiency Optimization and Wide ZVS Operation Range in Bidirectional Inductive Power Transfer System

IEEE transactions on industrial electronics (1982. Print), 2019
The efficiency of bidirectional inductive power transfer (BIPT) systems is strongly dependent on the load. Besides, the soft-switching operation of power switches is critical to high-frequency converter in the BIPT systems.
