Single-switch zero-voltage-switching high power factor electronic ballast

2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289), 2003
This paper introduces two modified Class E circuits to achieve low crest factor of lamp current. By integrating flyback topology with Class E converter, the modified circuits can achieve improved lamp current crest factor, and still maintain high power factor and zero-voltage-switching features in conventional Class E converter.

Zero-Voltage Switching in Full-Bridge Converter

Australian Journal of Electrical and Electronics Engineering, 2008
This 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,

Zero voltage switching full - Bridge converter topology

Intelec 2010, 2010
This paper describes a version of the Phase Shifted Full Bridge (PSFB) converter topology that achieves Zero Voltage Switching (ZVS) of the primary side controlled switches over a very wide load range, has minimal loss of output voltage due to commutation delay, that reduces the excess current flowing through the transformer and primary switches during

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.

A novel zero-voltage switched multiresonant converter

PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 2002
A novel approach is presented by which the switching frequency of a two-transistor zero-voltage-switched multiresonant converter (ZVS-MRC) is controlled in proportion to input voltage changes in order to maintain essentially constant efficiency over the input voltage range with a switching variation of only +or-10%.
