摘　　要：适应不同电池组的双向储能系统是当下分布式发电发展的关键,其中降低充放电电流纹波是评判整个储能系统的性能优劣的重要指标,为此提出了逆变与斩波的背靠背结构,使其能够适用于不同储能电池逆变器的拓扑结构,并针对电池充放电电流纹波较大的问题在直流侧引入了三重化结构,从而降低了电池充放电电流的纹波。Adapting to different kinds of two way storage is the key to the development of distributed generation,reducing the charge discharge current ripple is an important index for evaluating the performance of the whole energy storage system,so this paper puts forward a topology that the inverter and chopper back to back can be applied to different storage battery.The three-repetition structure is introduced on the DC side in order to solve the great of the charge and discharge ripple of current in the battery.

关 键 词：储能 三重化 电流纹波
