電流形インバータを用いた小容量電池電力貯蔵システムの特性

抄録

We propose an electric energy storage system with batteries by a current source inverter. It is interconnected to the single-phase three-wire distribution system. In order to reduce the dc reactor capacity and change the discharging and the charging operations by signals, a set of DC-DC converters is added between the inverter and the batteries. In this paper, the proposed circuit configuration, the control scheme and the operating method are described, and then the discharging and the charging characteristics are discussed experimentally.
