A novel control method for single-phase shunt active power filter

Lijuan Yin, Xilin Zhao, Zhan-qiang Xin, Haowen Luo

Abstract

This paper proposes a novel voltage control method for single-phase shunt active power filter (SAPF) using the space vector pulse-width modulation (SVPWM). The method provides compensation for harmonics and reactive power and has an excellent dynamic performance. A detailed analysis is presented for the principle of single-phase SVPWM. The APF's current reference is obtained by subtracting the measured load current from the supply current reference. MATLAB simulation result shows that the compensation effect of this kind of APF is very well in the case of load changes, and it can achieve flexible compensation. The validity of this APF processing system to compensate current harmonics and reactive power is substantiated by simulation and experimental results.
