Abstract :
This paper presents a novel control method for a shunt current quality compensator, which combines the current quality compensation and dc-link voltage control together. The proposed control method can be applied in single-phase, three-phase three-wire and three-phase four-wire active power filter and hybrid active power filter. Compared with conventional methods, the proposed method has a great reduction of computation steps, and both current compensation and dc-link voltage control processes are simplified into controlling the gain of a controller. Representative simulation results in a three-phase four-wire hybrid active power filter are presented to show the effectiveness of the proposed control method.
