The general trend of power electronics systems toward more compactness, extended lifetime, and higher operating temperatures yields a very high stress on the system. The concept of assuring reliability for power electronics in automotive applications consists of five parts. Two of them are concerned with the input - the description of the mission profile and of the system construction. The next steps are simulation calculations designed to optimise the electrical properties and the heat dissipation. These are followed by the risk analysis aimed at evaluating possible failure mechanisms. Accelerated reliability tests are used to verify the results of the risk analysis. The examples of a compact and high-temperature resistant power electronics module for an integrated starter-generator as well as a high temperature electronic control unit will be used to demonstrate this concept.
