In this paper the authors proposed a control algorithm for single phase active power filter to work under non stiff source. The method proposed compensate non linear load by improving the power factor to the desired value and also eliminate the harmonics under distorted Source voltage and source currents. A detailed synchronization circuit is presented for proper sequence of operation of the shunt active power filter. The active power filter (compensator) is realized using a single-phase voltage source inverter operated in a PWM hysteresis current control mode. The method is validated through simulation results using MATLAB. The results have been shown with ideal and practical compensator with an emphasis on dynamic performance.
