Abstract

In this paper, improved ZCS-PWM boost converter is proposed. The proposed converter eliminates additional conduction loss of a main switch by flowing circulating current oかy through an auxiliary switch. The operation modes of proposed converter are explained. And design procedure of resonant parameters is established. Experimental results are presented to verify the theoretic analysis of the proposed converter.

이 논문에서는 개선된 영전류 부스트 컨버터를 제안한다. 이 컨버터는 공진으로 인한 순환 전류를 보조 스위치와 인덕터를 이용해 보조 회로에만 흐르도록 하여 주스위치의 부가적인 도통 손실을 제거한다. 제한된 컨버터의 동작모드에 대해 설명하겠다. 또한 공진 파라미터의 설계를 설명하겠다. 제안된 컨버터를 5kw, 40kHz로 제작하여 실험결과를 토대로 확인하겠다.
