ARCHITECTURE OF INTERCONNECTED ELECTRONIC POWER MODULES FOR A ROTATING ELECTRIC MACHINE AND A ROTATING ELECTRIC MACHINE INCLUDING SUCH AN ARCHITECTURE

摘要

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.
