Abstract
Hybrid drives can substantially reduce the fuel consumption and the emissions of a motor vehicle and additionally increase the traveling comfort and the driving dynamics. Key components of these drives are an electrical machine and an inverter, which consists of many electronic elements. The electronics have to be operated at moderate temperatures, in order to use the full potential of a hybrid drive. For this reason today the inverter normally is arranged separately from the electrical machine into a separate housing. Advancements of the electronic elements in the last years make solutions tangible, which can also provide high power with high environmental and coolant temperatures and are able to work reliably over the specified life time of a motor vehicle. Furthermore, electronics for high operating temperature make variable mounting spaces possible, so the modularity of the hybrid components can be increased and the systems can be assembled in a more compact manner. In this document the requirements on the electronics and the necessary development for these environmental conditions are described
