摘　　要：基于双向变流器技术的蓄电池充放电装置具有充电和放电功能,同时实现了网侧电流正弦化及单位功率因数,因而减少了对电网的谐波和无功污染。对变流器工作在不同状态的相量图进行了分析,介绍了双环控制策略的结构及控制算法。最后给出装置的主电路和试验波形。The device for battery charge or discharge based on the technology of bidirectional converter can be used in charging or discharging battery, and realize sine wave of AC and unity power factor. Accordingly it reduces the pollution of harmonic and Var in power network. This phasor diagrams that converter operates different states are analysed. The structure and control algorithm of dual-loop control method are also introduced. Finally, the main circuit of device and experimental waveform are provided.
