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, 2013This 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, 2003By 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, 2002A 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.

New zero voltage switching PWM flyback converter
2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC), 2010In this paper a new zero voltage switching PWM flyback converter with simple auxiliary circuit is introduced. The auxiliary circuit is only composed of a resonant capacitor and an auxiliary switch connected to a tertiary winding on the converter main transformer.

Zero Voltage Switching isolated boost converter topology
2011 IEEE 33rd International Telecommunications Energy Conference (INTELEC), 2011This 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.

Zero-Voltage Switching in Full-Bridge Converter
Australian Journal of Electrical and Electronics Engineering, 2008This paper presents a comparison study of circuit topology of the voltage source type zero-voltage soft-switching (ZVS) full-bridge DC-DC power converter with an isolated high-frequency transformer employing phase-shift control. The switching power losses and voltage stress on the active devices are considerably reduced. A prototype operating at 10kHz,
