PC 파워 서플라이용 비대칭 하프브리지 DC/DC 컨버터의 초기 구동시 돌입전류 제거 기법

Abstract

This paper presents a start-up in-rush current reduction technique of asymmetry half-bridge DC/DC converter for PC power supply. The proposed converter is composed center-tapped half-bridge converter with blocking capacitor. The proposed converter can reduce the severe in-rush current when the proposed converter is power up. The validity of this study is confirmed from the experimental results.
