Abstract: The invention concerns a device (3) for synchronizing at least two DC/DC converters. It is characterized in that it comprises receiving means (21A, 21B, 23A, 23B) for receiving a switching signal generated by each of the converters; means (25) for detecting a transition type of the received switching signals; means (27) for generating a synchronization signal when a transition is detected; and means (27, S1, S2) for supplying the synchronization signal to one of the converters, said means (27, S1, S2) being configured to supply the synchronization signal to a different converter and in an order of succession each time a transition is detected.

Abstract: The invention relates to a power supply unit (3) for supplying power to an on-board electrical network of a vehicle, including: at least two DC-to-DC converters (9A, 9B) which are interleaved and reversible between an opera-ting mode for lowering voltage and an operating mode for raising voltage, the converters (9A, 9B) being intended for being connected to a power storage device (ST2) and being capable of supplying current to the on-board network; and a switch (K) enabling a power source (STI) to supply power to the on-board network when the switch (K) is in a first state, and enabling the power storage device (ST2) to supply power to the on-board network when the switch (K) is in a second state. The unit is characterized in that the converters (9A, 9B) are variable-frequency converters, and in that the power supply unit (3) also includes a synchronization unit (200) configured such as to synchronize the operation of the converters (9A, 9B) operating at variable frequencies and the current generation of the converters.
