DISPOSITIF DE CHARGE D'UNE BATTERIE DE VEHICULE AUTOMOBILE PERMETTANT DE COMPENSER LES HARMONIQUES, VEHICULE AUTOMOBILE DOTE D'UN TEL DISPOSITIF DE CHARGE ET PROCEDE DE CHARGE CORRESPONDANT

摘要

A battery charging device for a motor vehicle battery with at least partially electric traction includes a filtering stage to be connected to an electrical power supply network, a voltage buck stage connected to the filtering stage, a voltage boost stage coupled to the voltage buck stage and to be connected to the battery, and a regulation unit to impose chopping duty cycles on the voltage buck stage and on the voltage boost stage. The regulation unit compensates the harmonics generated by the voltage buck stage in the filtering stage, acting on the voltage buck stage.
