Abstract
A method for interconnecting electronic power modules of a polyphase rotary electric machine. The power modules are disposed in open cavities of a heat sink and comprise substrates on which are provided MOSFETs of a synchronous rectifier bridge and integrated control circuits. The method comprises the production of: a planar connector () including at least one layer of conductive traces (); a plurality of interconnection elements () arranged in multiple geometric formations and ultrasonically welded or brazed (S) directly to the substrates () and/or the MOSFETs; and openings () in the planar connector () allowing the free passage of the upper ends () of the connection elements () and a mechanical contact with the conductive traces (). The electrical connections are obtained by means of laser () transmission welding (S) or electric resistance welding.
