  ABSTRACT: This paper presents the performance of a three-phase three-wire SAPFs controlled with p-q theory and hysteresis current control. The reference harmonic currents are obtained using p-q theory, while a proportional-integral (PI) controller is used to keep the DC-link voltage constant. The hysteresis control generates switching signals for the inverter to inject compensating currents into the system. A MATLAB/Simulink model was built and tested with different nonlinear loads, such as resistive, inductive, capacitive, and unbalanced loads. The simulation results prove that the SAPFs can reduce the Total Harmonic Distortion (THD) from more than 28% down to below 5%, which satisfies the IEEE-519 standard. The results also show that the proposed method has a fast response and stable operation under changing load conditions. This study confirms that the SAPFs with p-q theory and hysteresis control is a reliable solution for harmonic reduction in power distribution systems.
