Abstract :
Distributed power systems are an attractive solution to meet the requirements (redundancy, modularity, battery backup, etc.) for the next generation of power supply systems. In addition, the normalization regarding power factor and total harmonic distortion makes it necessary to include power factor correction in the input stage in those architectures. This paper presents a novel approach of an integrated battery charger/discharger which offers power factor correction and battery galvanic isolation in a simple structure. Placing the battery into the primary side overcomes the need of galvanic isolation integration in each one of the DC/DC on-board converters when this topology is used as part of a distributed power supply systems
