ABSTRACT:
A battery charger includes a primary side circuit, a transformer, a secondary side circuit and a control circuit. The secondary side circuit includes a first output unit and a second output unit. The battery charges a main battery and an auxiliary battery. The first output unit, which is connected to a main battery, includes an integrated rectifier-converter and a smoothing circuit. The integrated rectifier-converter is formed using MOSFETs. When charging the auxiliary battery with power from the main battery, power from the main battery is converted by the integrated rectifier-converter to AC power which induces power in an output winding of a transformer connected to the auxiliary battery.
