Abstract
A power electronics inverter includes a housing which forms a cold plate with coolant passages. The housing encloses an insulated gate bipolar transistor (IGBT), and a DC Link capacitor. The capacitor comprises a bus-bar which exits from a bottom side of the capacitor, and the bus-bar is positioned adjacent to the cold plate. The cold plate forms a cooling passage which underlies the IGBT and the capacitor bus-bar. Thermally conductive gap pads are located between the capacitor bus-bar and the cold plate.
