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 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.

Zero-voltage-switching Three-phase T-type Inverter

2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia), 2021
A novel zero-voltage-switching (ZVS) three-phase T-type inverter and its control scheme are proposed, which can realize ZVS operation of all switches. The operation principle of the proposed ZVS T-type inverter is analyzed. Furthermore, the ZVS condition is derived and the voltage stress is analyzed.

Zero Voltage Switching isolated boost converter topology

2011 IEEE 33rd International Telecommunications Energy Conference (INTELEC), 2011
This paper describes an isolated boost converter topology that was invented and patented by the author in the early 80s' but has not been described in detail in an article before. As this converter has very interesting properties and appears to now be re-invented by others perhaps it is time for a paper to be written on it.

GTO characterization for zero voltage switching applications

PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 2002
GTO applications limitations are investigated under hard and soft switching topologies as device output power and device switching frequency are simultaneously increased. Characterization test results and a P-Spice GTO model simulating device turn-off are used in the investigation.
