ROTARY ELECTRIC MACHINE WITH REVERSIBLE MULTIPHASE DUAL VOLTAGE FOR A MOTOR VEHICLE, AND CORRESPONDING ELECTRICAL NETWORK WITH TWO SUB-NETWORKS

The rotating electric machine comprises a rotor (17) mechanically coupled to a thermal engine, a stator comprising first stator windings (19) connected to a first reversible inverter (20) connected to a first electrical power supply sub-network (2) of the motor vehicle having a first nominal direct voltage (V1), and second stator windings (21) connected to a second reversible inverter (22) connected to a second electrical power supply sub-network (5) having a second nominal direct voltage (V2) lower than the first nominal direct voltage (V1), a transfer circuit (26) comprising at least one switch (27) and electrically connecting a neutral point (28) of said first stator windings (19) to an output terminal (24) of the second reversible inverter. In accordance with the invention, the transfer circuit further comprises an inductor (34) for reducing iron losses of the stator arranged in series with the switch.
