Abstract: By the high-quality usage of power electronics devices which include rectifier, inverter, U.P.S, S.M.P.S, and speed drives and so on, many problems are introduced in power systems. One of such trouble is generation of current& voltage harmonics inflicting distortion of load waveform, voltage variation, voltage depression, heating of system and many others. This paper is an attempt to mitigate the harmonics by using different control method for the Shunt A.P.F. The different control techniques used in the proposed performance analysis are the d-q method using PI controller with current hysteresis controller and PI controller with SPWM controller. The other set of controller technique is the p-q method using PI controller with current hysteresis controller and PI controller with SPWM controller. The simulation of proposed circuit is done by using MATLAB& the results are tabulated and the performance evaluation is carried out.
