High temperature electronics for future hybrid drive systems

More and more, automakers are using hybrid drives and their advantages. Key components of these systems are an electrical machine and a converter, consisting of many electronic parts. This converter normally is arranged apart from the electrical machine in a separate housing. Thus the electronic components can be operated at moderate temperatures, in order to use the full potential of the hybrid system. But further developments of the electronic components in the last years make solutions tangible, which can provide high power with high environmental and coolant temperatures and are able to work reliably over the specified life time of the vehicle. The high temperature electronics 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 environmental conditions and the necessary requirements for the electronics are described.
