Abstract: this paper has proposed a novel method for the improvement of power quality (PQ) in a nonlinear system using active power filter (APF). The proposed topic incorporates Photovoltaic (PV) system, MPPT controller, fuzzy controller, dc link capacitor, voltage source converter (VSC) and nonlinear load. The switching gate pulses for the APF are generated by fuzzy logic controller (FLC) technique depending on instantaneous power balance theory. By this technique total harmonic distortion (THD) in the utility current can be minimized within IEEE norms. The advantage of FLC is faster response, better efficiency, no need for accurate mathematical models, capable of dealing with imprecise inputs and managing with non-linearity. In this paper 3- phase 3- wire system under unbalanced and balanced load conditions with APF and FLC is implemented. MATLAB / SIMULINK is used to demonstrate the system and a comparison of THD values at certain load conditions is presented.
