Power supply system and method on board an aircraft
First Claim
1. A power supply system of an aircraft, comprising:
- several generators powering with 230 volts A.C. several distinct electrical cores, wherein various loads of the aircraft are connected to each of these electrical cores, in which each electrical core includes;
an input driver,several identical power modules, each power module of the several identical power modules includes a network connection permitting connection to a controller and a synchronization line permitting connection to the other power modules,means for placing in parallel the several power modules including interconnection inductances between the power modules, and a switching matrix including a set of relays,means for controlling the relays of the switching matrix, so as to reconfigure all of these relays in an event of failure of a power module, thus working power modules can provide power that the failed power module can no longer provide,several output filters, andrelays of the switching matrix that may be connected to at least one load.

Abstract
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.
