<p>The invention concerns the electric power supply of airplanes and in particular large-size commercial airplanes. The invention is characterized in that the aircraft is equipped with an AC/DC converter which distributes power over a direct current network from a 230 volt three-phase alternating voltage applied to the main inputs (E1, E2, E3). The converter comprises an autotransformer which preferably has nine outputs (A1, A2, A3, B1, B2, etc.) for nine-phase rectifying. Said outputs are applied to an 18-diode rectifier bridge. When the aircraft is on the ground, the alternating power is supplied at 115 volts from a ground generator; it is applied through a three-phase connector (CAUX) to the auxiliary inputs (M1, M2, M3) connected to intermediate outlets of three-phase coils constituting the AC/DC converter.</p> |
