A method for managing operation of an aircraft system comprising at least one electrical energy storage set to be supplied with DC current connected to a DC current power supply bus, at least one electrical machine providing AC current by mechanical draw on a drive system connected to a current generation control unit, a bidirectional converter configured to convert a DC voltage into AC voltage, and a control module of the converter, the management method generating a command for the converter from the angular position (θ) of the electrical machine, from the intensity of the electrical current delivered by the electrical machine, and from the output electrical voltage of the converter.

Method for managing operation of an electrical power supply system of an aircraft comprising at least one electrical energy storage set

An electrical architecture of an aircraft includes a plurality of primary generators each associated with a propulsion engine of the aircraft, a plurality of primary electrical networks each associated with a primary generator in nominal operating mode, a single-part secondary electrical network, an electrical energy accumulation device connected directly to the secondary network, a first electrical energy converter arranged between the secondary electrical network and a first of the primary electrical networks, allowing energy to be transferred from the first of the primary electrical networks to the secondary electrical network, the first electrical energy converter being intended to supply electrical energy to the electrical energy accumulation device in nominal operating mode, a second electrical energy converter arranged between the secondary electrical network and a second of the primary electrical networks, allowing energy to be transferred from the secondary electrical network to the second of the primary electrical networks.

Electrical architecture of an aircraft

An electrical architecture for controlling inverters and to an aircraft includes the architecture. The electrical architecture comprises: a plurality of converters capable of operating independently of one another, each converter being intended to power a charge, associated with each converter/charge pair: a charging loop, comprising at least one sensor measuring a parameter that is characteristic of the operation of the charge, an operation control module, receiving an operation setpoint of the charge and information originating from the operation sensor, the operation control module controlling a current setpoint of the considered converter so that the information originating from the operation sensor follows the operation setpoint. The operation control module is common to the converters.

Electrical architecture for controlling converters and aircraft comprising the architecture

The monitoring of an electrical equipment item includes two electrically insulated circuits, a screen in the form of a film arranged between the two circuits, the screen comprising a substrate and a conductive filament arranged on the substrate, a module configured to circulate a current in the conductive filament and to monitor the current.
