AN INTEGRATED BATTERY CHARGER DISCHARGER WITH POWER-FACTOR CORRECTION/

Distributed power-supply systems are an attractive solution to meeting the requirements (redundancy, modularity, battery backup, etc.) for t he next generation of power-supply systems, In addition, the normaliza tion regarding power factor and total harmonic distortion (THD) makes it necessary to include the power-factor correction in the input stage in those architectures, This paper presents a novel approach of an in tegrated battery charger/discharger which offers power-factor correcti on and battery galvanic isolation in a simple structure, placing the b attery in the primary side overcomes the need of galvanic isolation in tegration in each one of the dc/dc on-board converters when this topol ogy is used as part of a distributed power-supply system.
