A device for transferring power by an electrical energy transformer, and in particular by a magnetic coupler, including on a primary side a primary winding in series with an alternating source and on a secondary side a secondary winding, a rectifier bridge, and a load. The rectifier bridge includes two diodes arranged in series with the secondary winding and two MOS transistors also in series with the secondary winding. The load is connected on the one hand to a point common to the two diodes and on the other hand to a point common to the two MOS transistors. A mechanism is provided for switching the MOS transistors in such a way that they are simultaneously in the ON state for a predetermined duration. Such a device may find application to cases of weak coupling between a primary side and a secondary side.
