The power supply modules, together feeding a load (between the terminals 13 and 12) with the voltage V0, comprise blocking diodes D1 (or D2). A feedback loop controls the output voltage (controller 14 and comparator 15 which receives Vref1 (or Vref2)). Two output voltage terminals are used for locking, on the two electrodes of D1, the voltages V1 and V0 (or D2 with the voltage V2 and V0), and are connected to inputs of output voltage selection means (31) which are suitable to supply either the voltage kV0 (k</=1) when D1 (or D2) is conductive, or the voltage kV1=Vref1 (or kV2=Vref2) when D1 (or D2) is blocked.
