The rectification stage () having: The two interphase inductors (A,B) have a common core () which defines a magnetic circuit and all the windings of the two interphase inductors (A,B) are wound on this common core for the magnetic coupling thereof.

Stage for rectifying a three-phase current

The power supply interface () includes a rectification stage (), having an autotransformer () connected to a power supply network (), and a signal conditioning stage () having an output () supplying power to a load (). The conditioning stage () includes a power module (), for conditioning the power supply signal, and a control module () designed to control the power module (). An autotransformer () includes at least one additional winding (A,B,C;A,B,C) connected to the control module () to supply it with electrical power, the or each additional winding being magnetically coupled to at least one primary winding (A,B,C) of the autotransformer (). The power is supplied to a motor in an airplane.
