  • Architecture of interconnected electronic power modules for rotary electrical machine, and rotary electrical machine comprising architecture of this type
    Patent number: 9680356
    Abstract: An architecture of interconnected electronic power modules for a polyphase rotary machine, includes electrically interconnected power modules (5) and a connector (6) including one or more layers formed by pluralities of conductive traces borne by plates, such as to connect the power modules (51 to 53) to one another and to electrical elements of the rotary machine. The power modules (51 to 53) include a plurality of connection elements (510 to 530) brazed directly to components of the power modules (51 to 53) and, in the upper part, to conductive traces of the connector (6). This architecture includes a heat sink (4) equipped with open cavities (41 to 43) for receiving the power modules (51 to 53). A polyphase rotary machine is also provided using such an architecture, in particular a dual three-phase alternator with synchronous rectification.

  • Process for interconnection of electronic power modules of a rotary electrical machine, and assembly of interconnected power modules obtained by means of this process
    Patent number: 9601973
    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 (6) including at least one layer of conductive traces (64); a plurality of interconnection elements (512) arranged in multiple geometric formations and ultrasonically welded or brazed (S2) directly to the substrates (51) and/or the MOSFETs; and openings (65) in the planar connector (6) allowing the free passage of the upper ends (5120) of the connection elements (512) and a mechanical contact with the conductive traces (64). The electrical connections are obtained by means of laser (8) transmission welding (S1) or electric resistance welding.
