ZVS Resonant Converter With Series-Connected Transformers

IEEE Transactions on Industrial Electronics, 2011
This paper presents a new series-resonant converter with series-connected transformers in order to realize zero voltage switching (ZVS) for power switches, zero current switching (ZCS) for rectifier diodes at full load, less transformer secondary winding with a full-wave rectifier, and load current sharing. Two series-resonant converters using the same

Newly Designed ZVS Multi-Input Converter

IEEE Transactions on Industrial Electronics, 2011
A newly designed zero-voltage-switching (ZVS) multi-input converter is proposed in this paper. The converter can boost the different voltages of two power sources to a stable output voltage. An auxiliary circuit is employed for achieving turn-on ZVS of all switches in the proposed converter.

A New Family of Full-Bridge ZVS Converters

IEEE Transactions on Power Electronics, 2004
A family of soft-switched, full-bridge (FB) pulse-width-modulated (PWM) converters that feature zero-voltage-switching (ZVS) of all bridge switches over a wide range of input voltage and output load with minimal duty cycle loss and circulating current is described.

The ZVS-PWM Active-Clamping CUK Converter

IEEE Transactions on Industrial Electronics, 2004
A CUK converter featuring clamping action, pulsewidth modulation, and soft-switching commutation is proposed to overcome the limitations of the conventional CUK converter. As the resonant circuits absorb almost all parasitic reactances of switches, including transistor output capacitances, this converter is suitable for high-frequency operation ...

Study of Boost Converter Based on the ZVS

2016 International Symposium on Computer, Consumer and Control (IS3C), 2016
In order to reduce the switching loss and turn-off voltage spikes, opened current spikes, soft-switching technology has made great progress in application of switching power supply technology. Zero voltage switching (ZVS) can improve the efficiency of switching power supply and realize the high frequency switch power supply. The method based on the ZVS

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,

Kříž zv. královny Dagmar

2021
At the end of the 17th century, a small enameled cross was discovered in one of the royal graves in Saint Bendt's church in Danish Ringsted. According to the record of the administrator of the Danish Royal Treasury, the cross was found in the grave of the Danish Queen Dagmar - the daughter of the King of Bohemia, Ottokar I (+1230).

Implementation of the ZVS converter with synchronous rectifier

IEE Proceedings - Electric Power Applications, 2006
The paper presents the system analysis and circuit design of a half-bridge zero-voltage-switching (ZVS) flyback converter with synchronous rectifier. The leakage inductance and output capacitance of active switches are used to realise ZVS operation during the transition state between two switches.
