Abstract
This paper presents a new positive/negative pulse battery charger with energy feedback and power factor correction. The positive/negative pulse battery charger is composed of a single-stage boost-forward converter and a flyback converter. The single-stage boost-forward converter not only completes the positive pulse-charging mode, but also achieves high power factor for the charger. By using the flyback converter, the energy is released from the battery to the boost output capacitor in the negative pulse-discharging mode. Thus, the efficiency of the charger can be increased. A prototype circuit is implemented to verify that the analysis and design are effective and feasible.
