Abstract

Three-phase AC-DC flyback converter with high power factor correction and tight regulation is presented in this p paper. The advantage of the proposed converter does not require expensive high voltage and high cun‘ent devices that a are normally needed in popular boost type 3-phase converter. In this paper the detailed small signal analysis of the m modular 3-phase AC-DC flyback converter is provided for control purposes and also experimental results are included t to confirm the validity of the analysis.

본 논문에서는 우수한 출력전압 조절 기능과 높은 역률을 갖는 3상 AC-DC flyback 컨버터를 제안한다. 제안한 컨버터의 장점은 보통 부스트 형의 3상 컨버터에서 쓰이는 가격이 비싼 고전압, 대전류의 소자를 필요로 하지 않는다. 본 논문에서는 제어 목적으로 3상 AC-DC flyback 컨버터에 대해서 소신호 해석을 하였고 실험결과는 분석의 타당성을 확증한다.
