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-Switching Voltage Doubled SEPIC Converter

2011
A zero-voltage-switching (ZVS) voltage doubled single-ended primary inductor converter (SEPIC) is presented in this paper. An active clamp circuit is added to the conventional isolated SEPIC converter to clamp the voltage across the switches and provide ZVS operation.

Voltage Unbalance Compensation Method with Zero Voltage Switching for Series Connected Switching Devices

2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019
This paper proposes a voltage unbalance compensation method of series-connected switching devices for high voltage application such as DC distribution systems. In the series connection, a turn-off voltage unbalance occurs in switching devices due to a parasitic parameter mismatch and a switching timing mismatch among switching devices. In this paper, a

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.

A zero voltage switching flyback converter topology

PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 2002
A zero voltage switching flyback power converter topology employing an auxiliary circuit is presented in this paper. The proposed power converter has lossless switching (whatever the line and load conditions), few components and can be operated either in voltage or current mode control.
