Development of the Power Supply with Reduced Conduction Loss and Switching Stress on the Full-Bridge DC-DC Converter

풀브리지 DC-DC 컨버터의 도전손실과 스위칭 스트레스를 저감한 전원장치 개발

This paper is indicating the problems, which are the conduction loss on the high frequency transformer, the protection of rectification diode as the snubber loss and the stress of switching main devices, as be made high current and high speed in the phase-shift switching full-bridge DC-DC converter is used the power supply's main circuit of high capacity. In this paper, to improve those problems, it is proposed that is the resonant circuit auxiliary can be reduced conduction losses and stabilized output control. And, it is constructed prototype of the power supply as the result of computer simulations.
