Electric power supply method and architecture for on-board domestic network

An electric power supply method for a domestic network placed on board a passenger cabin using a domestic equipment, requiring voltage levels of a terrestrial domestic type, the method comprising with primary electric power sources being supplied over at least two primary networks:

• connecting the primary networks in parallel to a single on-board domestic network for powering said domestic equipment in the cabin through interfaces for converting primary alternating current into domestic level voltage and frequency, with each primary network being coupled to the domestic network through at least one interface;
• parallelizing the conversion interfaces by a measurement of a level data of electric parameters supplied by each interface for regulating a sharing of the primary power sources according to their availability and supplying a consistent service level over a domestic network;
• maintaining a quality criterion of each primary network and for a domestic quality of the domestic network by filtering, compensating a level and correcting a power factor in each conversion interface linked upstream with each primary network and linked downstream with the domestic network;
• and
• wherein each conversion interface integrates a galvanic isolation electric transformer splitting an avionics neutral point of a corresponding primary network and a neutral point from one of the primary networks.
