摘要

The operating theory of control system for an active power filter (APF) is expounded in this paper. According to the instantaneous power balance equation between the AC and DC side of an APF, the dynamic mathematical model of DC voltage close loop control in d-q-0 coordinates is derived. The stability criteria under proportional-integral (PI) control and some important conclusions about the influence of parameters in main circuit on system stability are obtained. Making optimization designs for some parameters of controller and digital simulation for system performance shows that theoretical analysis is valid.
