This paper introduces the structure and functions of the conventional Unified Power Quality Conditioner(UPQC)briefly. Moreover,a novel single phase UPQC based on the DC Isolation(DCI) unit is proposed and implemented.

• 介绍了统一电能质量调节器(Unified Power Quality Conditioner,简称UPQC)的传统拓扑结构,设计并实现了基于直流隔离单元(DC Isolation,简称DCI)的新型DCI-UPQC实验样机。
