Abstract
A device for charging a battery, for example of an electric traction motor vehicle, based on a single-phase power supply network, the device including a filtering stage configured to be connected to the single-phase network, a voltage step-down stage connected to the filtering stage, a voltage step-up stage configured to be connected to the battery and coupled to the voltage step-down stage via an inductive component or an induction coil, and a regulating unit configured to impose chopping duty ratios on the voltage step-down stage and on the voltage step-up stage. The regulating unit compensates for phase shift between an input current of the voltage step-down stage and an input voltage of the voltage step-down stage.
