Mixed device for controlling power transfer between two cores of a direct current network and supplying an alternating current motor
View Patent ↗A combined device for instantaneous control of power transfer between two cores of a direct current network and for powering an alternating current engine. The device includes: an assembly of two three-phase inverters, each including three switching cells connected to the engine, which engine includes three stator windings connected to the two three-phase inverters, and a module for controlling the assembly, which ensures both an adjustable direct current power transfer and enables stabilization of the direct current voltage of one of the two cores if it is not connected, and the control of the engine.
1. A combined device for an aircraft which controls power transfer between two decentralized cores of a direct current network and which powers an alternating current motor, comprising:
a first core of the two cores, to which is connected a first alternator via a first stabilized alternating-direct current rectifier module, is positioned in a first area of the aircraft;
a second core of the two cores, to which is connected a second alternator via a second stabilized alternating-direct current rectifier module, is positioned in a second area of the aircraft, the second area being separated from the first area by a significant distance,
the first core and the second core are connected to a plurality of charges for the aircraft;
an assembly of two three-phase inverters, each three-phase inverter of the two three-phase inverters including three switching cells connected to the motor, the motor includes three stator windings whose ends are connected to the two three-phase inverters; and
a module that controls the assembly, which ensures both an adjustable direct current power transfer and stabilization of direct current voltage in balancing the powers supplied by the two alternators, and the control of the motor.
2. The device according to claim 1 , wherein each switching cell comprises two switches unidirectional in voltage and bidirectional in current.
3. The device according to claim 2 , wherein each switch includes a transistor associated with a diode in an anti-parallel structure.
4. The device according to claim 1 , wherein the first core is also connected to a first direct-direct current module and the second core is also connected to a second direct-direct current module.
5. The device according to claim 1 , wherein one charge of the plurality of charges is an electromechanical actuator.
