Abstract:
Reliability and lifetime are key parameters for power electronics in all kinds of applications, but especially in the automotive domain. Therefore, the project HiEFFICIENT was started to investigate these parameters with different approaches likes physics of failures as well as with data driven methods. This shall enable predictive health management on component and sub-system level. Additionally, the project iREL4.0 approaches the topic one level deeper by enabling zero failure electronic components and systems manufacturing. This session will discuss the issue of power electronics reliability along the whole value chain – from chip to system.
