Abstract
A device for charging a battery, in particular a battery of an electric traction motor vehicle, on the basis of a single-phase power supply network, including a filtering stage intended to be connected to the single-phase network, a voltage step-down stage connected to the filtering stage, a voltage step-up stage intended to be connected to the battery and coupled to the voltage step-down stage via an inductive component such as an induction coil, a regulating unit able to impose chopping duty ratios on the voltage step-down stage and on the voltage step-up stage. The regulating unit includes means for compensating for the phase shift between the imput current of the voltage step-down stage and the imput voltage of the voltage step-down stage.
