Résumé / Abstract
The automobile and aeronautics present both harsh environment for power electronics with both ambiant elevated temperatures and thermal cycling. This paper introduce works engaged in our both laboratories in this research field, in cooperation with other partnairs, for these domain of applications. Then, particular study about the lifetime assesment of power igbt modules dedicated to traction of hybrid car is presented with a discussion about the hypothesis of linear accumulation of the cyclic fatigue damage.
