Abstract

In the Phase Shifted Full Bridge(: PSFB) converter, there are several design factors including power switches, power switches' driving circuits, transformer and inductor, and rectifier stage, etc. Among them, a key factor influencing an optimal performance of the PSFB converter is the design of transformer. Especially, its effect becomes more important in low voltage and high power applications. In this paper, a study on an optimal design of transformer in the PSFB converter is presented. The design equations for the transformer are derived and analyzed in details, and an example design of the transformer for a 12V, 1200W server power supply application is showed as the result of analysis.

위상변조 풀브리지 컨버터를 설계, 개발하는데 있어, 전력반도체와 그 전력반도체 구동회로, 변압기 및 인덕터, 정류기 등을 포함한 많은 설계 요인들이 존재한다. 그 중에서 위상변조 풀브리지 컨버터의 최적 성능에 매우 큰 영향을 끼치는 것은 변압기 설계이다. 특히 변압기 설계는 대형 컴퓨터 데이터센터에 사용되는 전원장치에서처럼 저전압, 고전류 응용에서 매우 중요하다. 이 논문에서는 위상변조 풀브리지 컨버터의 최적 성능을위한 변압기 설계에 관한 연구 결과를 발표한다. 변압기 설계에 관련된 설계 수식들을 유도하고 세밀한 분석을 한다. 이를 토대로, 12V, 1200W 서버전원장치 응용을 위한 위상변조 풀브리지 컨버터 최적 성능을 위한 변압기 설계를 결과물로 제시한다.
