This paper presents some results of the joint research project "Electric Components for Active Gears (EfA)". The cooling of the power electronics is done by the cooling circuit of the combustion engine which can reach temperatures up to 105°C, in worst case up to 125°C. Therefore, the power devices must withstand temperatures up to 200°C. Main Challenge is the power cycling capability. With improved packaging technologies, this requirement can be fulfilled. Systematic power cycling tests were performed to address different failure modes and to evaluate the improvement capability. An improvement of power cycling lifetime of a factor of 100 was found with new interconnection technologies.
