蓄电池模拟装置主电路的拓扑及控制研究

Study of Power Circuit and Control Method on Battery Simulator

蓄电池模拟装置在用电设备进行设计或检测时可以反复地、长时间地进行检测作业,可以提高效率并节约成本[1]。蓄电池模拟装置对于其功率电路的功能要求有:网侧可回馈电能,具有一定的动态跟随特性。本文设计了一种单相供电的网侧可回馈拓扑结构,一定程度上满足了蓄电池模拟装置对功率电路的功能要求。

Battery simulators obviously increase effeciency and save cost because simulators can operate lastingly and repeatly compared with real batteries. Basic demands o11 simulators＇ power circuits are line regeneratable function and fast dynamics features. Recently, most designers take PWM converter as simulator power circuits, it increases complexity of control method and power loss. This paper designs a new power circuit supplied by single-phase and be capable of regenerating power to the line.
