Abstract—In this paper, we present a Hybrid Power Filter (HPF) which consists of a combined system of Passive Filter (PF) and Series Active Power Filter (SAPF) has been designed by MATLAB/SIMULINK approach for harmonic and reactive power compensation. This filter is a three level PWM voltage source inverter and we use a Fuzzy Logic Controller (FLC) algorithm to control the harmonic voltages. The viability of the proposed algorithm is validated in this work. This combined system of filter is able to compensate the reactive power (showed that source voltage is sinusoidal and in phase with source current), and harmonics (voltage & current) for three phase of the non linear load current proposed with RL load. For the following voltage related problems in the power grid voltage flicker and voltage unbalance in three-phase systems are minimized under norm. The proposed solution has achieved an improvement of power quality in distribution system;
