In this paper, Performance of Shunt active power filter (SAPF) is analyzed for various types of non linear loads. Among the various control schemes available for SAPF, in direct current control scheme is used here. PI controller and fuzzy logic controller are used to analyze its performance for various types of nonlinear loads (R, DC motor, Induction motor). The output parameters are Total Harmonic Distortion (THD) and p ower factor. The results are obtained with the conventional PI controller and fuzzy controller. The proposed method offer an efficient control method under the various load conditions results in power factor improvement and THD reduction. Simulation of the proposed controller (PI and fuzzy logic controller) of a shunt active power filter has been carri ed out in MATLAB/SIMULINK and the aim is to reduce the THD and improve the power factor.
