Performance improvement of shunt active power filter with combined control technique

Recently Many researchers are focussing to improve the power quality in Power system network using active power filter. This paper Specifically presenta a newely developed method to enchance the power quality. In this work A Fuzzy Hysteresis along with Synchrous detection technique controller is developed to Control and Regulate the DC Capacitor voltage, Generation of switching signals and generation of reference currents, Fuzzy implemention in the Active filter enchance the quality simultaneously tuning with hysteresis current controller, Generation of compensating Signals compenstaes the harmonics produced by the non liner load and results a Fundamental signal. The designed filter is modeled and investigated having Non linear load using MATLAB/Simulink. Various simulation results are presented to verify the effectiveness of the proposed controller in the shunt active power filter which can be used in Three Phase and Single Phase System in Power Network.
