Zero-voltage-switching converters with multi-resonant bipolar switch

Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002
Full-wave mode operation of zero-voltage-switched (ZVS) power converters may be losslessly implemented by splitting the resonant capacitor across both the active switch (MOSFET) and the series diode. By appropriately choosing the relative size of each capacitor, charge otherwise trapped inside the MOSFET output capacitance at turn-on may be ...

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 ...

A simple zero-voltage-switching boost converter

Proceedings IEEE Southeastcon '98 'Engineering for a New Era', 2002
In this paper, a new type of PWM boost zero-voltage-switching converter is presented. The new soft-switching converter is formed by adding only two auxiliary components to a conventional boost converter, namely: an active switch and a resonant inductor. The voltage stresses on both the main and auxiliary switches are fixed at V/sub g/+V/sub o/ and they

Zero voltage switching series resonant based UPS

PESC 98 Record. 29th Annual IEEE Power Electronics Specialists Conference (Cat. No.98CH36196), 2002
This paper presents a novel single-phase UPS topology based on series resonant power converters. Among the features of the proposed topology are: (i) zero voltage switching for all power converters that comprise the UPS; (ii) inherent protection against short-circuits in the load; (iii) high quality output waveforms even when operating at no load or ...

Zero voltage switching approach for flyback converter

[Proceedings] Fourteenth International Telecommunications Energy Conference - INTELEC '92, 2003
A zero voltage switched flyback power converter which realizes soft switching for every semiconductor is proposed. The sinusoidal resonant current flows through the secondary side rectifier diode and zero current switching of the diode is realized. Diode recovery is not generated.

Zero voltage switched chopper with SiC-MOSFETs

2013 IEEE Energy Conversion Congress and Exposition, 2013
This paper describes a study applying SiC-MOSFETs to soft switching topology with ZVS (zero voltage switching) and evaluating performance of new dc-dc converter when compared with conventional one with silicon IGBTs. Soft switching topology is SAZZ (snubber assisted zero voltage zero current transition) proposed for high frequency, high efficiency and ...

PWM boost converter with zero-voltage-switching

[Proceedings] 1992 IEEE International Conference on Systems, Man, and Cybernetics, 2003
By adding a second transistor, a zero-voltage-switched (ZVS) quasi-resonant boost converter can be shown to be controllable using a constant frequency control scheme. The new topology differs from a zero-voltage-switched quasi-resonant boost converter by the addition of an extra switch in parallel with the resonant inductor.

A Zero-Voltage Switching Three-Phase Inverter

IEEE Transactions on Power Electronics, 2014
A new modulation scheme for the active clamping zero-voltage switching (ZVS) inverter is proposed. With the proposed modulation scheme, the inverter can realize ZVS operation in all switching devices and can remarkably suppress the reverse recovery current in insulated-gate bipolar transistor's antiparallel diodes as well.
