A single switch battery charger with active power filter: article / Muhamad Taufiq Ramly

This paper present the battery charger with active power tilter for minimizing the input current distortion in a single phase system. The striking feature of this circuit is that it contains only a single switch. The active power filter here is use to mitigate the distortion current by injecting equal but opposite current to shape the pulsating of the supply current to a sinusoidal form that Is In-time phase with the supply voltage. In this work, the single switch active power filter is used to reduce switching stress, losses and also the cost.
