In order to make more effective control of universal power quality controllers (UPQC), an outer loop model for the voltage loop in a three-phase three-wire UPQC is proposed in the paper.
In this paper, two types of main power circuits and their control methods are introduced when constructing active power filter in three phase four wire system.
