A device (1) for charging a battery (13), comprising: a resistive-inductive-capacitive-type filter stage (2) to be connected to a three-phase network, a voltage buck stage (3), and a voltage boost stage (4) to be connected to the battery (13), as well as an induction coil (Ld) disposed between the buck stage (3) and the boost stage (4). The device (1) comprises a regulating unit (15) which can impose chopping duty cycles on the voltage buck (3) and boost (4) stages. The regulating unit (15) comprises: means (16) for compensating the phase shift induced by the filter stage (12) between the currents (Ie1, Ie2, Ie3) and the voltages (Ve1, Ve2, Ve3) tapped off from each phase (B1, B2, B3) of the three-phase network, and means (16, 17) for maintaining the amplitude value of the current passing through the coil (Ld) above a predefined nonzero threshold. |
