C. Aguilar et al., AN INTEGRATED BATTERY CHARGER DISCHARGER WITH POWER-FACTOR CORRECTION/, IEEE transactions on industrial electronics, 44(5), 1997, pp. 597-603
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.
