Abstract: This paper presents a three-phase three-wire series active power filter to compensate voltage harmonics perturbation for specific and sensible loads at distorted supply network. The conventional configuration is based on two-level voltage source inverter with hysteresis controller requiring a complex and a complicated mathematical model. To overcome this drawback and improve the series APF capability, a new control scheme using fuzzy control techniques is adopted in this work. Today fuzzy logic controllers are successfully employed in various industrial applications; their advantages are robustness and easy implementation. The proposed fuzzy voltage controller is designed to improve compensation capability of series active power filter by adjusting the voltage error using a fuzzy rule. The control strategy use instantaneous reactive power theory easy to implement and gives an excellent performances. The simulation is performed using MATLAB-Simulink and SimPowerSystem BlockSet Toolbox. The simulation results from complete structure including control and power circuits are presented and discussed.
