This paper presents a comprehensive study to design a shunt active power filter (SAPF) that effectively removes voltage and current harmonics, thus meeting the power quality requirements of the utility grid supply. The design incorporates a proportional-integral (PI) controller for DC-link voltage regulation, and the extraction of reference currents is based on the instantaneous reactive power theory. Hysteresis current control is employed to generate gate signals for controlling the 2-level voltage source inverter (VSI) switches. The SAPF design is implemented and simulated using MATLAB, Simulink block sets, considering both uneven nonlinear loads. Simulation results demonstrate that the projected filter successfully reduces harmonic distortion below the levels specified by the IEEE-519 std.
