Abstract: The present invention relates to a supply device comprising at least two energy converters (10, 20), a common output (4) and a local output (2, 3) per converter. The converters are connected in redundant mode so as to deliver a DC supply voltage (V0) on the common output, their coupling being effected by means of blocking diodes (13, 23) from whose cathode the DC supply voltage (V0) stems. Each converter includes a loop for slaving the voltage on the common output and an independent local slaving loop for delivering a sufficient voltage on the corresponding local output (17, 27) irrespective of the state of the blocking diode (13, 23) of this converter.
