Abstract

A novel soft-switching power converter with high power factor is presented in this paper, discussed power factor corrector topology and dc/dc converter with passive lossless soft-switching based on a ML4803 IC control. DC/DC converter is adopted a novel two-transistor forward soft-switching technique, which realizes zero-voltage turn-on and turn-off, with no additional switches. A 48V/10A communication power supply module is developed in this paper. It has the characteristics of rapid dynamic response, high power factor, high efficiency and small bulk ect.
