ZCS 보조회로를 이용한 ZVT Boost 컨버터에 관한 연구 = A Study on ZVT Boost Converter Using a ZCS Auxiliary Circuit

다국어 초록 (Multilingual Abstract)

Recently, a ZVT boost converter is embedded in a power factor correction system. The control circuit of the converter assures soft-switching for all the MOSFETs and load regulation The PFC system contains additional control circuits which assure the input voltage in a sinusoidal form and feed-forward line voltage regulation. In this paper, a soft switching boost converter with zero-voltage transition(ZVT) main switch using zero-current switching(ZCS) auxiliary switch is proposed. Operating intervals of the converter are persented and analyzed. The proposed results show that the main switch maintains ZVT while auxiliary switch retains ZVT whiles auxiliary switch retains ZCS for the complete specified line and load conditions.<br/>
