초록
본 연구는 배터리 전력저장장치(BESS)를 위한 새로운 양방향 컨버터에 대한 기술이다. 제안된 토플로지는 일반적으로 사용되고 있는 DAB(Dual Active Bridge) 컨버터의 효율을 더 높일 수 있게 설계되었다. 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 커플링-인덕턴스를 연결해 충전시 벅(Buck Converter)동작하고, 방전시 부스트(Boost Converter)동작하는 양방향 컨버터를 설계했다. 커플링 인덕턴스로 이전의 DAB Converter보다 효율적으로 승/강압한다. 이 실험은 차후 ESS, BESS와 UPS의 전압을 승압시키는 시스템의 연구에 적용될 수 있다. 이 토플로지는 LV단에 커플링 인덕턴스로 일반적인 DAB Converter 와는 달리 VMC(Voltage Mode Control) 외에도 CMC(Current Mode Control) 이 가능하다. 실험은 컴퓨터 시뮬레이션인 PSIM을 사용하여 제어 시스템 성능이 우수하다는 것을 입증하였다.
Abstract
This study aims to find a new technology of bi-directional converter for battery electric power storage device. The generally DAB(Dual Active Bridge) Converter is connected with switch(8), transformer(1) and inductance(1). It can constitute a large-capacity/low-voltage battery with ten times higher step-up/step-down ratio and soft-switching function. To obtain Step-up/step-down ratio 10 times higher and Soft-switching function to achieve a high efficiency, the toplogy is able to compose the high capacity/low voltage battery. It operates efficiently the proposed DAB converter better than the DAB converter from coupling inductance. The toplogy is operated during charge buck converter operation and during discharge boost converter operation. This experiment can be applied to the study of the system for boosting the voltage of a future ESS, BESS the UPS. It toplogy can use operating Voltage Source Control and Current Source Control. This paper proves to use computer simulation that is PSIM and is excellent control system.
