Abstract: ABSTRACT In the past, the majority electrical power system equipment and electronics were made to generate nearly sinusoidal waves of current and voltage. However, due to the current trend, interest, and extensive use of power electronics devices for commercial, industrial, and residential consumers, electronics equipment no longer operates with a perfect current and voltage waveform due to natural harmonics. To do so reduce harmonic currents resulting from non-linear loads, conventional passive filters were first used. However, the constraints of passive filters, such as their large size, bulk, and propensity for resonances in series and parallel with supply impedance, limit their usefulness. Active power filters are currently available as a dynamic as well as practical way to reduce harmonic with current taken by non-linear loads due to the shortcomings of passive filters. This work proposes the modeling and modeling of switch off the active power filter to reduce the harmonic currents drawn by loads that are not linear. The active power filter was controlled by a fuzzy logic controller (FLC) due to its robustness, ease of use, and lack of need for mathematical modeling of the system. were carried out using the SIMPOWER toolbox environment and MATLAB/SIMULINK. The simulation results showed that the total harmonics distortions (THD%) fell inside the suggested IEEE 519-2014 standard harmonic limitations. In reducing the current harmonic drawn by the nonlinear load, the suggested controller has demonstrated a strong and dynamic reaction.
