Abstract
The quality of electric power plays an important role on supply side as well as user side. The quality of electric power is polluted by using non-linear electronics load. As the use of electronics devices increases day by day for the fast and reliable operation and for the automation are the main sources of harmonics in the power system. Traditionally Passive filters are used for improve the power quality. The inadequate performance of the conventional passive filter techniques to reduce harmonics problems has affirm to introduce active filters. The active filters have many functions like isolation, filtering, damping., load balancing and reactive power compensation. the paper explores a brief review on SAPF for 1-phase,3- phase 3 wire, 3-phase 4 wire and control techniques along with new correction and practical aspects for future research in the area of SAPF.
