ABSTRACT:
The power supply modules, together feeding a load (between the terminals 13 and 12) with the voltage V.sub.0, comprise blocking diodes D.sub.1 (or D.sub.2). A feedback loop controls the output voltage (controller 14 and comparator 15 which receives V.sub.ref1 (or V.sub.ref2)). Two output voltage terminals are used for locking, on the two electrodes of D.sub.1, the voltages V.sub.1 and V.sub.0 (or D.sub.2 with the voltage V.sub.2 and V.sub.0), and are connected to inputs of output voltage selection means (31) which are suitable to supply either the voltage kV.sub.0 (k.ltoreq.1) when D.sub.1 (or D.sub.2) is conductive, or the voltage kV.sub.1 =V.sub.ref1 (or kV.sub.2 =V.sub.ref2) when D.sub.1 (or D.sub.2) is blocked.
