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 ...

Switching to zero voltage in Josephson tunnel junctions
Solid State Communications, 1971Abstract We have observed that Josephson tunnel juctions biased at non-zero voltage will often fail to enter the zero-voltage state when the current bias is swept through zero at modest rates. This occurs as the result of a previously unrecognized facet of the dynamics of the Josephson effect.

Zero-voltage-switched interleaved flyback converter
INTELEC 2009 - 31st International Telecommunications Energy Conference, 2009This paper proposes an interleaved flyback converter which is remarked with zero-voltage-switched active switches and reduced reverse recovery loss on the rectifying diodes. The configuration is composed of two identical flyback converters and an auxiliary inductor shunted between the diodes.

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,

IEEE Transactions on Industrial Electronics, 2011
A new multioutput forward converter is proposed. It consists of four synchronous switches in the secondary side for two outputs with the same ground. The primary switches control the main output voltage, and the synchronous switches in the transformer secondary side control the auxiliary output voltage. The main advantages of the proposed converter are

Analysis and design of a zero voltage switching dc-to-ac inverter
Proceedings of First International Caracas Conference on Devices, Circuits and Systems, 2002In this paper, the authors present a simplified steady state analysis and design for a DC-to-AC inverter with zero-voltage-switching (ZVS) and output isolation. It is a current-fed power converter having variable frequency control to obtain a symmetrical regulated AC output.

A new zero-voltage switching DC/DC boost converter
IEEE Transactions on Aerospace and Electronic Systems, 1993A pulsewidth-modulated (PWM) zero-voltage-switching quasi-resonant boost converter operating at constant switching frequency is presented. In contrast to the frequency-modulated (FM) zero-voltage-switching quasi-resonant boost converter, this converter possesses better controllability and higher operating performance, and overcomes the instability ...

Zero-voltage switching for the neutral-point-clamped (NPC) inverter
IEEE Transactions on Industrial Electronics, 2002This paper proposes a transformer-assisted pulsewidth-modulation zero-voltage-switching neutral-point-clamped (NPC) inverter. With the assistance of a transformer-assisted small-rating lossless auxiliary circuit, the main switches work with zero-voltage switching without suffering from any voltage/current spikes, under simple explicit control.
