This article describes a Synchronous reference frame based current control scheme for three phase shunt active power filters (SAPFs) to reduce or to remove harmonics, correct power factor, and balance asymmetrical load is analyzed. This active power filter (APFs) is used to compensate harmonic currents and reactive power generated from the nonlinear loads. In this article, to determine reference compensation currents under balanced source voltages, the voltage source inverter for harmonic filtering of a three phase shunt active filter is used. In this proposed method, a fuzzy gain scheduling controller is used and the response of the DC link voltage is compared with PI controller during transient and steady state. The main objective of this article is to analyze shunt active filters with fuzzy gain scheduling controllers and PI controllers. To carry out this analysis, active and reactive current methods (Id–Iq) are considered. Extensive simulations were carried out. The simulations were performed under balance sinusoidal conditions. The results validate the dynamic behavior of a fuzzy gain scheduling controller over PI controllers. The simulation of the proposed system is evaluated using MATLAB Simulink and the results show that the proposed method is more effective than the existing methods.
