변압기 전압 되먹임방식을 이용한 고역률의 리셋권선을 갖는 새로운 포워드 컨버터

Abstract

A new reset winding clamped forward converter with transformer voltage feedback technique for power factor correction with a single-switch/single-stage is proposed. The proposed converter gives the good power factor correction, low current harmonic distortions, and tight output voltage regulation. The prototype shows the IEC555-2 requirements are met satisfactorily with nearly unity power factor.
