Abstract: The power supply interface (10) includes a rectification stage (18), having an autotransformer (40) connected to a power supply network (12), and a signal conditioning stage (20) having an output (28) supplying power to a load (14). The conditioning stage (20) includes a power module (22), for conditioning the power supply signal, and a control module (24) designed to control the power module (22). An autotransformer (40) includes at least one additional winding (62A, 62B, 62C; 64A, 64B, 64C) connected to the control module (24) to supply it with electrical power, the or each additional winding being magnetically coupled to at least one primary winding (44A, 44B, 44C) of the autotransformer (40). The power is supplied to a motor in an airplane.

Abstract: A device for producing electricity, the device comprising a three-phase alternator comprising three windings, a rectifier for converting the AC delivered by the alternator into rectified current, and a voltage-raising chopper using the self-inductance of the alternator to raise the voltage. The device includes a switch unit enabling the three windings to be connected either in a star configuration when the alternator is being rotated to produce electricity, or else to the respective phases of a three-phase network when the alternator is stopped.
