Battery charger with active power filter / Nor Syahidah Abdullah

This paper describes the battery charger with active power filter using simulation and hardware. The active power filter is use to mitigate the distortion current by injecting equal but opposite current to shape the pulsating of the supply current to sinusoidal form that is in phase with the supply voltage. Full bridge rectifier is converting AC to DC voltage. Capacitor at dc side to stored the voltage. A diode rectifier feeding capacitive-resistive load is consider as nonlinear load on ac mains for the elimination of harmonics by the proposed active power filter. The microcontroller PIC16F877A will implement the APF fully. For this project, the active power filter is use to reduce switching stress, losses and the cost
