Application Research on An Improved Active Power Filter

Han Ru-cheng

Abstract

In this paper,the basic principle of active power filter(APF),the methods of harmonic and reactive current detection and the compensation current control in circuit were introduced,and an improved method was proposed.The whole shunt APF system was simulated by MATLAB/Simulink.The results show that APF controlled by triangle pulse comparison method can compensate the harmonic and reactive current quickly.
