Abstract:
An electric drive unit having a multi-phase electric motor and an inverter with a plurality of power semiconductors, an inverter mount, and a plurality of busbars. The power semiconductors are mounted to the base of the inverter mount in an annular arrangement and with the terminals of the power semiconductors extending through the base. Each of the busbars has a first busbar portion, which includes a first body and a set of first fingers that are fixedly coupled to the first body, and a second busbar portion that includes a second body and a set of second fingers that are fixedly coupled to the second body. Associated fingers in the first and second sets of fingers of each bus bar are mechanically and electrically coupled to opposite sides of a corresponding one of the terminals.
