The invention relates to the electrical power supply of aircraft and notably of large commercial aircraft. According to the invention, the aircraft is equipped with an AC-DC converter that distributes power over a DC network starting from a three-phase alternating voltage of 230 volts applied to its main inputs (E 1 , E 2 , E 3 ). The converter comprises an autotransformer which preferably has nine outputs (A 1 , A 2 , A 3 , B 1 , B 2 , etc.) for a nine-phase rectification. These outputs are applied to a rectifier bridge with 18 diodes. When the aircraft is on the ground, the AC power is delivered at 115 volts from a ground generator; it is applied via a three-phase connector (CAUX) to auxiliary inputs (M 1 , M 2 , M 3 ) connected to intermediate taps of the three-phase windings forming the AC-DC converter.
