Design of High Quality Regulator with High Efficiency Based on Half-Bridge Topology

하프 브릿지 컨버터를 기반으로 한 고효율을 갖는 고역률 정류기의 설계

Design of single stage AC/DC converter with high power factor and high efficiency based on half-bridge topology for low power application is proposed. To obtain design equations, modelling and detailed analysis are performed. The proposed converter gives and power factor and high efficiency by employing aynchronous rectifiers. To verify the performances of the proposed converter 90W-converter has been designed. This prototype converter meets IEC555-2 requirements with near unity power factor.
