병렬 연결 배터리 모듈 시스템을 위한 새로운 충ㆍ방전기

A novel integrated battery charger/discharger converter for a standardized battery module is proposed. Instead of using separate charger and discharger converters, it integrates these two converters into a single converter in order to minimize the size. The integrated charger! discharger converter not only regulates the solar array output power including the peak power tracking capability but also controls the battery charging/discharging current depending on the solar array output power and the load power. In addition, It offers a regulated bus voltage which simplifies the power distribution/conversion for the pay load
