The goal of this study is to use the Series Active Power Filter (SAPF) to mitigate voltage issues on the three-phase system in terms of voltage sag. The design and modeling of a three-phase SAPF for voltage compensation of non-linear loads are presented in this study. Simulations in MATLAB/Simulink are used to verify the performance of SAPF design using ANN controller and compared to the conventional PI controller. The concept of this technique is by inserting SAPF between the source and nonlinear load. Then, if the system has problem with voltage sag, the injection of harmonic voltages (vf) across the coupling transformer into voltage load in order to maintain the voltage load in normal condition. To maintain a clean sinusoidal voltage waveform across the nonlinear load, the injected harmonic voltages are added/subtracted to/from the source voltage. In this case, the ANN controller based on the back-propagation technique is applied to tune the appropriate parameters of controller during voltage sag issue. The result shows ANN controller is better than PI controller in term of percentage error of voltage sag and total harmonic distortion (THD). © 2022 IEEE.
