Non-Isolated High Current Battery Charger with PFC Semi-Bridgeless Rectifier
In this paper a unidirectional non-isolated high current battery charger with power factor correction (PFC) is proposed. The structure of the battery charger is divided in two parts: a bridgeless PFC at the input stage and a interleaved Buck converter at the output stage. The structure uses multi-interfase transformer, to allow the magnetic volume reduction, and a bridgeless PFC rectifier to reduce the number of components. This paper presents the converter operational stage analysis, control and simulation results.For a 48V battery with 32A constant current of charging, the proposed converter reached a power factor of 0.9938.
