Physics-of-degradation and Monitoring for Power Electronic Converters

Abstract:


With the ever increasing reliability requirements, zero-failure-period is a must for some industry applications, e.g., automotive. Traditional reliability tools dealing with failure, such as physics-of-failure, accelerated lifetime test, lifetime prediction, are not sufficient and applicable any more. The understanding of the degradation process along with time and mission profile becomes essential, while there are limited study for power electronics components and converter systems, from this perspective. Monitoring the degradation process and operation status becomes important and a demand for those applications. Both of these two aspects create new challenges in power electronic converters which require an investigation in both scientific modeling and practical implementation issues. The topic of this project will be a combination of component-level physics-of-degradation and converter-level data analytics, aiming for the application in converter systems.
