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.

Mixed device for controlling power transfer between two cores of a direct current network and supplying an alternating current motor

Electrical emergency source device located on an aircraft

A device for controlling power transfer between two cores of a direct current network, in which the cores, which are source-charge interconnection nodes, include protective and contact members, placed in different areas of a power distribution system in which the direct current network is installed. The device includes an electronic power converter including two switching cells mutually interconnected by an inductance, wherein each switching cell includes two switches, and a module for controlling the converter, which ensures both a controllable direct current power transfer and stabilization of the direct current voltage.

Voltage inverter provided with four switching cells (Qto Q) to be connected to the terminals of a DC voltage source (Vdc), each comprising two semiconductor switches (I, I, I, I, I, I, I, I) installed in series, these switches having a common point (A) to be connected to an AC current source (Mac) with three phases (p, p, p) and a neutral (n), the connection being made onto one phase (p, p, p) for three of the cells (Q, Q, Q) and onto the neutral (n) for the fourth cell (Q). Each cell (Qto Q) cooperates with a semiconductor electrical isolating device (S, (Sand S)) to be put into a turn-off state if the cell should fail, this isolating device (S, (Sand S)) being arranged either on the connection to the AC current source (Mac), or on connections to the terminals of the DC voltage source (Vdc).
