A battery charger is for a motor vehicle that includes a primary electrical power converter and a secondary electrical power converter connected by a transformer. The charger includes: a compensating primary electrical power converter, having a high-frequency switching stage connected at the output to the transformer; a filter capacitor connected between two input terminals of the high-frequency switching stage of the compensating primary converter; a compensating secondary electrical power converter connected to the compensating primary converter via the transformer; and a switchable storage capacitor connected between the two input terminals of the high-frequency switching stage of the compensating primary converter. The compensating secondary electrical power converter and the high-frequency switching stage of the primary compensation converter charge or discharge the storage capacitor as a function of an instantaneous power setpoint.
