In HEVs, the level of power electronic integration in the powertrain is determined by a number of constraints. Not only installation area, cooling, vibration loading and temperature stressing must be regarded as essential factors, but also assembly, service, flexibility and responsibilities within the added value chain. Most of all, the costs must be included in the general concept from the very beginning. Shape, volume and packaging of the power electronics are significantly influenced by these constraints. The operation of power electronics at elevated coolant temperatures and junction temperatures of up to 200 deg C intensifies the demands on the life time of the incorporated components. Such demands cannot be met with the current state of the art. This contribution will describe an integration approach, which considers the above mentioned constraints and leads to a generally space invariant design of a hybrid transmission (active transmission, Aktivgetriebe). The requirements of assembly and service are taken into account. Such hybrid transmission can be implemented as a variant to standard series drive trains; a fact that simplifies integration in existent cars.
