A novel approach for achieving ZVS operation in class-D ZVS inverter

2017 IEEE 12th International Conference on Power Electronics and Drive Systems (PEDS), 2017
This paper presents a novel approach to fulfill the zero-current switching (ZVS) operation of the class-D ZVS inverter by utilizing the anti-parallel diode of transistor actively which enables a switching-timing allowance to be produced. The switching-timing allowance of the class-D ZVS inverter at any duty ratio is derived.

A ZVS-PWM inverter using a simple ZVS-PWM auxiliary commutation pole

2011 6th IEEE Conference on Industrial Electronics and Applications, 2011
A new zero-voltage-switching (ZVS) pulsewidth-modulated (PWM) single-phase inverter using a simple ZVS-PWM auxiliary commutation pole is presented in this paper. Except for the auxiliary switches, all active and passive semiconductor devices in the ZVS-PWM single-phase inverter operate at ZVS turn on and turn off. The auxiliary switches operate at zero-

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.

An Improved ZVS PWM Three-Level Converter

IEEE Transactions on Industrial Electronics, 2004
This paper proposes an improved zero-voltage-switching pulse-width-modulation three-level converter (ZVS PWM TLC), which is improved from the original ZVS PWM TLC just by exchanging the position of the resonant inductor and the transformer, such that the transformer is connected with the lagging switches.

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).

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

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.

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.
