Abstract: An aircraft propulsion system includes a turbomachine and at least one electric motor. The motor includes a first half-motor and a second half-motor that include, respectively, a first stator and a second stator cooperating with a common rotor of the motor. The propulsion system further includes at least one first energy source (B) capable of delivering a DC voltage and at least one electric generator (PMG) driven by the turbomachine. The electric generator generates an AC voltage to form a second energy source and is associated with an active rectifier that transforms the AC voltage into a DC voltage. The value of the DC voltage is controlled by the active rectifier, the output of which is connected to the first energy source.

Abstract: An electronic current-switching system comprising a driver unit and a current-switching device with one controlled transistor, a control unit coupled to said transistor, a power supply unit of the control unit and a digital communication bus transmitting to the control unit a first control signal of the driver unit. The power supply unit comprises: a transformer, an integrated circuit including a clock input coupled to a second output of the driver unit delivering a second control signal having the form of a pulsed signal with an adjustable duty cycle, and an output delivering to the transformer a primary voltage signal dependent on the second control signal, and a voltage divider bridge measuring the frequency-domain signal delivered by the transformer.
