A device and method for coupling two parts of a dc network, in which at least two capacitors respectively are installed, particularly onboard an aircraft. The device includes at least one static converter including at least one electronic coupling device, including at least one transistor and one diode, associated with an inductance, arranged between these at least two capacitors.

Device and method for coupling two parts of a DC network, particularly in an aircraft

A device and a method for emergency electricity supply on board an aircraft, able to supply a part of the aircraft's electrical power circuit. The device includes a synchronous machine with separate excitation, associated with a flywheel, and an auxiliary device to set the flywheel in rotation and to maintain rotation of the flywheel.

Device and method for emergency electricity supply on board an aircraft

The invention relates to a system and a method for supplying power to an aircraft comprising several generators supplying alternating current to several different primary electrical master boxes (and), the various aircraft loads being connected to each of these master boxes. This system comprises conventional master boxes (and) which supply power loads and at least one master box () devoted to actuator loads, this at least one devoted master box being connected to conventional master boxes.

System and method for supplying power for actuators on board an aircraft

A system and a power supply method, on board an aircraft, in which the power supply system of an aircraft includes several generators powering with 230 volts A.C. several distinct electrical cores, wherein the various loads of the aircraft are connected to each of these cores. Each core includes an input driver, several identical power modules, means of placing in parallel several power modules including interconnection inductances between power modules, and a switching matrix including a set of relays, means of piloting the relays of the switching matrix, so as to reconfigure all of these relays in the case of failure of a power module, several output filters, and relays of the switching matrix that may each be connected to at one load.

Power supply system and method on board an aircraft
