Zero-current switching switched-capacitor quasiresonant step-down converter
IEE Proceedings - Electric Power Applications, 2002Current stress is usually high for conventional switched-capacitor converter circuits, because of short-circuiting when charging up the capacitors. In this paper, two zero-current switching switched-capacitor resonant step-down converter families are presented which can improve the current stress problem. They are able to provide 1/2 to 1/n, and -1 to -

A zero-current-switching PWM flyback converter with a simple auxiliary switch
IEEE Transactions on Power Electronics, 1999A simple and effective approach of turning an isolated hard-switched converter design into a soft-switched one is presented. By adding an auxiliary winding, switch and small capacitor to the conventional pulsewidth modulation (PWM) isolated flyback converter, all switches and diodes are softly turned on and off. No extra active or passive voltage clamp

Class-E zero-voltage-switching and zero-current-switching rectifiers
IEEE Transactions on Circuits and Systems, 1990A number of class-E, half-wave and full-wave, zero-voltage-switching (low dv/dt), zero-current-switching (low di/dt), and mixed-mode rectifiers are introduced and verified experimentally. The rectifiers are derived from conventional rectifiers by adding reactive components.

Zero-voltage-switching/zero-current-switching soft-switching dual-resonant converter
International Journal of Electronics, 2010A soft-switching converter with dual resonant structures is presented in this article. The dual resonant tanks are composed of the leakage inductors and resonant capacitors to achieve a zero-current-switching (ZCS) turn-off mechanism for diodes on the secondary side of the transformer. Moreover, the voltage stresses of power switches are clamped by the

A near zero current switching series resonant inverter using GTOs
15th Annual Conference of IEEE Industrial Electronics Society, 1992The authors present a novel implementation of fast gate turn-off thyristors (GTOs) for a series resonant converter operating above 10 kHz and at an output power rating of 10 kW or greater. A zero current switching gating strategy that eliminates the need of large negative gate drive circuits is presented.

A New Family of Zero-Current-Switching (ZCS) PWM Converters
IEEE Transactions on Industrial Electronics, 2005A new family of zero-current-switching (ZCS) pulsewidth-modulated (PWM) converters which uses a new ZCS-PWM switch cell is presented in this paper. The main switch and auxiliary switch operate at ZCS turn-on and turn-off, and all the passive semiconductor devices in the ZCS-PWM converter operate at zero-voltage-switching (ZVS) turn-on and turn-off ...

Zero-current-switching PWM dc/dc converters
38th Midwest Symposium on Circuits and Systems. Proceedings, 2002An existing idea for a ZCS quasi-resonant converter was extended to generate families of zero-current-switching PWM dc/dc converters. The converter output voltage is regulated by controlling turn on of the auxiliary switch while both main and auxiliary switches maintain the ZCS and/or ZVS condition during the constant frequency operation.
