Abstract :
This paper discusses the different structures of power quality compensator (PQC), and mainly illustrates the influences on its voltampere (VA) rating and compensatory performance, which is exhibited under the condition that the AC input of main circuit´s DC supply is extracted from the system or the load side. Meantime, the impacts on PQC are also analyzed when a three-phase rectifier or PWM rectifier is adopted as the DC supply. The simulation results verify the correctness of the theoretical analysis
