Abstract

A new ZVT PFC for using 3[KW] power amplifier is proposed. Generally, the single phase diode rectifier has been widely used in the SMPS of the conventional power amplifier. But this rectifier has occurred some problems which are the input power factor and current harmonics. To solve the above problems, in this paper, two topology is adopted. The one is the boost type PFC for improving the input power factor. The other is the ZVT resonant circuit for reducing the switching loss and stress. In this paper, the proposed topology is analyze designed to built the ZVT PFC for using 3[KW] power amplifier. In order to verify the circuit va finally, the PSPICE simulation and experiment results are presented.
