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/zero-current-switching soft-switching dual-resonant converter

International Journal of Electronics, 2010
A 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

Class-E zero-voltage-switching and zero-current-switching rectifiers

IEEE Transactions on Circuits and Systems, 1990
A 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.
