摘　　要：本文提出了一种新型的单相统一电能质量调节器拓扑结构,该结构采用直流单元多组电容并联的方法来进行系统和装置间的隔离以取代传统的变压器隔离的方法。文中分析了这种结构的直流储能单元功率传递的原理,给出了参数设计的基本方法。给出了该装置并联单元、串联单元及直流单元的控制方法。文末给出了该拓扑的统一电能质量调节器的仿真及实验结果,证明了该拓扑的实用性和控制方法的有效性。A novel single phase UPQC based on the structure of DC unit isolation is proposed. The DCI-UPQC is isolated from the power grid by parallel connection of several capacitors in DC-link unit instead of transformer isolation in series or parallel unit. The relations between indices of the device and parameters of the DC unit are analyzed. The control method of a DCI-UPQC is also proposed. In the end, the simulation and experiment results are given to validate the practicability of the topology and the effectiveness of the control method.
