A novel ZVS direct coupling converter (DCC)

PESC Record. 27th Annual IEEE Power Electronics Specialists Conference, 2002
A novel DC-DC power converter with a ZVS topology is introduced. An amplitude modulated squarewave train is generated and the output can be controlled by the amplitude of this squarewave train. As energy is directly transferred to the output, it is known as a direct coupling converter (DCC).

ZVS Boost Converter with Wide ZVS Range

2011
A zero-voltage-switching (ZVS) boost converter with wide ZVS range is proposed in this paper. A ripple-free cell is added to a conventional two-switch boost converter. The ripple-free cell provides a ripple-free input current and ZVS operation of two switches. Due to the ZVS feature, the switching loss is significantly reduced.

Interleaved ZVS Converter With Ripple-Current Cancellation

IEEE Transactions on Industrial Electronics, 2008
In this paper, an interleaved soft-switching converter with ripple-current cancellation is presented to achieve zero- voltage-switching (ZVS) turn-on and load current sharing. In order to achieve ZVS turn-on, an active snubber is connected in parallel with the primary winding of the transformer.

Analysis, Design, and Implementation of a Parallel ZVS Converter

IEEE Transactions on Industrial Electronics, 2008
A soft-switching converter is presented in this paper to achieve a zero-voltage-switching (ZVS) turn on for all switches. Two half-bridge converters with asymmetric pulsewidth-modulation scheme are connected in parallel to control the output voltage at the desired value and achieve load-current sharing. Based on the output capacitance of power switches

ZVS Resonant Converter With Series-Connected Transformers

IEEE Transactions on Industrial Electronics, 2011
This paper presents a new series-resonant converter with series-connected transformers in order to realize zero voltage switching (ZVS) for power switches, zero current switching (ZCS) for rectifier diodes at full load, less transformer secondary winding with a full-wave rectifier, and load current sharing. Two series-resonant converters using the same

Newly Designed ZVS Multi-Input Converter

IEEE Transactions on Industrial Electronics, 2011
A newly designed zero-voltage-switching (ZVS) multi-input converter is proposed in this paper. The converter can boost the different voltages of two power sources to a stable output voltage. An auxiliary circuit is employed for achieving turn-on ZVS of all switches in the proposed converter.

The ZVS-PWM Active-Clamping CUK Converter

IEEE Transactions on Industrial Electronics, 2004
A CUK converter featuring clamping action, pulsewidth modulation, and soft-switching commutation is proposed to overcome the limitations of the conventional CUK converter. As the resonant circuits absorb almost all parasitic reactances of switches, including transistor output capacitances, this converter is suitable for high-frequency operation ...

Design methodology of resonant inductor in a ZVS inverter

2014 IEEE 5th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2014
In a zero-voltage switching (ZVS) inverter, the resonant inductor is used to realize soft-switching aimed at dynamic loss reduction under high switching frequency conditions. For this purpose, the losses on the resonant inductor should be low enough to ensure a significant loss decrease for the whole system.

A family of ZVS-CV low harmonic rectifiers

PESC97. Record 28th Annual IEEE Power Electronics Specialists Conference. Formerly Power Conditioning Specialists Conference 1970-71. Power Processing and Electronic Specialists Conference 1972, 1998
A new class of single-switch low harmonic boost-type rectifiers suitable for both single- and three-phase applications is introduced in this paper. All the semiconductors in these rectifiers operate with zero-voltage switching and clamped voltage (ZVS-CV) with minimum voltage stress, while the d.c.-side diode turns off at zero current.
