چکیده
1 This work is supported by NSF (contract number NSF 99 608 03) Abstract-A single-stage power factor correction converter with soft-switching is proposed in this paper. Besides the ZVT turn-on performance of the main switch, the converter has ZCS for the auxiliary switch with an active snubber. High frequency operation of the proposed converter makes the ac-dc power supply possible to be minimized in size and weight. A 50-W 500kHz prototype has been built in the laboratory to experimentally verify the analysis.

An Improved Design for Zvt Dc-dc Pwm Converters with Snubber Assisted Auxiliary Switch
This paper proposes an improved design to calculate the snubber auxiliary elements of ZVT DC-DC PWM converters with snubber assisted auxiliary switch. The proposed improved design guidelines are based on the reduction of the conduction losses through the auxiliary circuit. It is accomplished by the unique location of the turn-off snubber capacitor, which is shared by both active switches. By me...

Abstract: Attributing to the advantages of high efficiency, low electromagnetic interference (EMI) noise and closest to the pulse-width-modulation (PWM) converter counterpart, zero-voltage-transition (ZVT) PWM soft-switching inverters are very suitable for high-performance applications. However, the conventional control algorithms intended for high efficiency generally results in voltage distor...
