摘　　要：研究了面向蓄电池储能的双向AC-DC装置,给出了主电路的拓扑结构,该结构由AC-DC和DC-DC两部分组成,且有相互独立的控制环节,实现了电网侧与蓄电池侧控制系统的完全解耦。在此基础上分析其双向变流原理,并给出系统在蓄电池充电模式和供电模式下的控制框图。仿真与实验结果表明,电网侧电流正弦化及实现单位功率因数整流,在蓄电池供电时,系统输出标准正弦电压,且动态性能良好。The bidirectional AC-DC equipment was designed for the battery energy storage, the topological structure of the main circuit was given. Independent control links were owned by the topological structure. The control system was completely realized decoupling between power grid side and battery side. The principle for bidirectional converter was analyzed. The system control diagram base on the battery charging mode and supply mode was given. The simulation and experiment results show that Current sine and Unit power factor on power grid side are achieved,when the battery supply, standard sine voltage is output,dynamic performance is well of the system.
