Abstract
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, E, E). The converter comprises an autotransformer which preferably has nine outputs (A, A, A, B, B, 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, M, M) connected to intermediate taps of the three-phase windings forming the AC-DC converter.
