  • Drive train for a motor vehicle comprising an electric machine
    Publication number: 20070284157
    Abstract: In a drive train for a motor vehicle, with a converter bell arranged between an internal combustion engine and a transmission, and a drive shaft extending through the converter bell and carrying a clutch device and an electric machine together with a power converter, which comprises at least one capacitor and power electronics which are integrated into the converter bell, the capacitor and the power electronics are arranged between a stator of the electric machine and the converter bell such that they are distributed around the outer circumference of the electric machine in the radial direction and the capacitor and the power electronics are arranged such that they are in thermally conductive contact with the cooling system for the stator of the electric machine.

  • Power module with improved transient thermal impedance
    Patent number: 6812559
    Abstract: An electronic power module includes at least one electronic power device, a DCB ceramic substrate, a heat sink and at least one additional thermal capacitance. The electronic power devices are connected by a sintered layer on their underside to an upper copper layer of the DCB ceramic substrate. The upper copper layer of the DCB ceramic substrate is structured into copper conductor tracks for electrically contacting the power devices. The lower copper layer of the DCB ceramic substrate is connected by a sintered layer to a heat sink. The upper sides of the power devices are connected by a sintered layer to an addition thermal capacitance.
