Abstract

This paper proposes a new commutation circuit for a PWM Cuk AC-AC converter. The proposed commutation circuit utilizes a modified Undeland snubber as a commutation aid. The snubber circuit has some good features such as reduction of voltage/current stress of the main switches and improved efficiency. The experiment results show the adaptability and feasibility of the proposed commutation circuit.

본 논문에서는 PMW Cuk AC-AC 컨버터를 위한 새로운 commutation 회로를 제안한다. 제안된 commutation 회로는 컨버터 전류의 commutation을 위하여 개선된 Undeland 스너버를 이용한다. 개선된 스너버 회로는 주 스위치의 전압/전류 스트레스 저감, 효율 개선과 같은 장점을 갖는다. 본 논문에서는 실험을 통하여 제안된 commutation 회로의 효과와 적용 가능성을 확인하였다.
