Abstract
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.
