This paper presents the optimization of shunt active power filter parameters based on fuzzy logic control. The current active filter control is based on constant, fuzzy hysteresis band techniques, which are employed to derive the switching signals and also to choose the optimal value of the decoupling inductance. The DC voltage controller optimizes the energy storage of the DC capacitor, where proportional integral and fuzzy logic controllers are employed. Simulation results, obtaining using MATLAB/SIMULINK under several loads configurations, are presented and discussed. They show the effectiveness of fuzzy logic controllers in optimizing the PWM technique and the values of the passive parameters of the active filter.

Keywords: active power filter (APF), fuzzy logic control, optimization, harmonics, PWM techniques
