Efficiency optimisation of ZVS isolated bidirectional DAB converters [PDF]
IET Power Electronics, 2018 This study presents a control method for isolated bidirectional dual‐active‐bridge converters to optimise the efficiency by achieving the zero‐voltage switching (ZVS) in high‐voltage applications, which the switching losses are the major issues. At light‐load condition, the duty control algorithm is proposed to achieve the ZVS for all switches while ...

Asia-pacific Journal of Multimedia Services Convergent with Art, Humanities, and Sociology, 2016 본 연구는 배터리 전력저장장치(BESS)를 위한 새로운 양방향 컨버터에 대한 기술이다. 제안된 토 플로지는 일반적으로 사용되고 있는 DAB(Dual Active Bridge) 컨버터의 효율을 더 높일 수 있게 설 계되었다. DAB Converter는 스위치 8개, 변압기 1개, 인덕턴스 1개로 구성하고 10배 이상의 높은 승/ 강압비, soft-switching 기능으로 대용량/저전압 배터리를 구성할 수 있다. LV(Low-Voltage)단에 커플 링-인덕턴스를 연결해 충전시 벅(Buck Converter)동작하고, 방전시 부스트(Boost Converter)동작하는 양방향 컨버터를 설계했다.
