AB  - Shunt Active Filter (SAF) has been used since last decade for power quality improvement. This study
gives variable gain based fuzzy PI controller to control SAF to reduce total harmonic distortion factor whose
level goes high when power electronic based non-linear loads are connected with the supply. Three phase
voltage source inverter is designed to provide 180° shifted waveforms of the harmonics generated in the
system. Performance of the SAF depends on DC link voltage control. The results of DC link voltages are
compared with PI controller. This is all simulated with non-linear loads like bridge rectifier in continuation with
unbalanced loads. The inferences prove that the SAF together with variable gain based fuzzy PI controller work
effectively for different firing angles of non-linear load.
