Study of Boost Converter Based on the ZVS
2016 International Symposium on Computer, Consumer and Control (IS3C), 2016In 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

Gate driver circuit for ZVS mode
2016 XXV International Scientific Conference Electronics (ET), 2016This 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 new forward ZCS-ZVS converter
1996 IEEE International Symposium on Circuits and Systems. Circuits and Systems Connecting the World. ISCAS 96, 2002This paper presents a steady-state analysis with complete characterization of the converter operation. The non-dissipative snubber associated with a forward converter provides the soft commutation switching. The proposed approach allows building a converter with high frequency operation. A detailed analysis of the operation is presented.

A Novel ZVS-PWM Single-Phase Inverter Using a Voltage Clamp ZVS Boost DC Link
2007 2nd IEEE Conference on Industrial Electronics and Applications, 2007A 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 ...

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, 2006The 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.
