A Novel Charger/Discharger for the Parallel Connected Battery Module System

병렬 연결 배터리 모듈 시스템을 위한 새로운 충.방전기

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.
