Abstract
Recently, Electric power quality has become significant in the both power suppliers side and end user side. The electrical power system polluted because of non-linear loads used in the system. Utilities always looking for cost effective and improved power quality (PQ) solutions. Initially, the conventional method of passive filtering enrich to mitigate the PQ problems. The inadequate performance of the conventional passive filter techniques to mitigate PQ problems has affirm to introduce advanced power electronic based topologies in the improvement of PQ. Shunt active power filter (APF) is well established to mitigate PQ problems like current harmonics, reactive power demand and poor power factor in the distributed electrical power system. This study gives a brief review on shunt APF configurations for single-phase (two-wire), three-phase three-wire (3P3W) and three-phase four-wire (3P4W) systems and compensation control techniques for sinusoidal and non-sinusoidal voltage supply conditions. Additionally, latest improvements, practical aspects of implementation and some future research fields to carry out in the field on shunt APF.
