摘　　要：将有源功率因数校正技术引入UPQC直流储能单元的电压控制。详细阐述了其工作原理,给出了电压控制器和电流控制器的数字控制方法,消除了充电电流中的谐波和无功电流,储能单元电压稳定,能够应对输入电压变化的工况,动态性能良好。The active power factor correction （APFC） technology is introduced into the DC energy storage unit of UPQC for capacitive voltage control. Its working principle is explained, The design methods of voltage and current controllers are demonstrated with APFC technology, A case of active power factor correction （APFC） is represented. The validity of this design is tested by simulation. The results show that the harmonies and reactive current in charging process are eliminated.
