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.
