A novel zero-voltage switched PWM boost converter

Proceedings of PESC '95 - Power Electronics Specialist Conference, 2002
A novel, zero-voltage switched (ZVS) PWM boost converter that combines soft-switching with constant frequency operation is proposed in this paper. This converter can be operated with PWM control at a fixed frequency because ZVS operation is achieved with a simple auxiliary resonant circuit that is activated for only a small fraction of the switching ...

Novel zero-current-switching-zero-voltage-switching converters

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
A new family of zero-current-switching-zero-voltage-switching (ZCSZVS) pulse-width-modulation (PWM) converters are proposed. With the proposed ZCSZVS concept, the PSPICE simulation results of the application to a single-switch three-phase PFC rectifier have been obtained and compared with those of hard-switching and ZCT applications in order to show ...

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

Nonisolated Bidirectional Zero-Voltage-Switching DC–DC Converter

IEEE Transactions on Power Electronics, 2011
A new nonisolated bidirectional zero-voltage-switching (ZVS) dc-dc converter is proposed. The proposed converter can operate with ZVS, fixed switching frequency, and a ripple-free inductor current regardless of the direction of power flow. To provide ZVS of the power switches and a ripple-free inductor current, the proposed converter utilizes a very ...

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%.

Half-bridge zero-voltage switched multi-resonant converters [PDF]

, 2016
A half-bridge zero-voltage-switched multi-resonant converter. The converter basically comprises a device for converting an input voltage signal to a DC output signal to be imposed across a load. The device includes input terminals for receiving the input signal and output terminals for imposing the DC output signal across the load.
