Perspectives of Inverter Integration in Vehicle Powertrains

This paper describes new approaches for integrating inverters into electrified powertrains. Conventional solutions are dominated by separated inverters and e-machines with extensive electric and cooling interfaces in between. Generally the emachine is combined or integrated in the gearbox. Consequently the integration of the power electronics into this package is the next step to achieve a highly integrated mechatronic module. Two specific solutions will be introduced: one solution for hybrid traction application with a double inverter and one solution for an electric-driven axle e.g. for a fully electric or fuel cell vehicle.
