Topics
Thermal modeling of power electronic components is essential for predicting temperature distribution and ensuring reliable operation under varying electrical loads and environmental conditions. Accurate thermal models help in designing effective cooling strategies and preventing overheating-related failures. However, detailed thermal simulations often involve complex, high-dimensional systems that are computationally intensive. Model order reduction techniques address this challenge by simplifying these complex thermal models into lower-order representations while preserving essential dynamic characteristics. This reduction significantly accelerates simulation times and facilitates real-time thermal management and control in power electronics systems without compromising accuracy.
Learning Outcomes:
- How to model power electronic ECUs and components using 3D Finite Element simulation. (Example Full Bridge)
- How to perform 1D, 2D, and 3D model order reduction
- Introduction to the TherMOS toolkit (freely available on GitHub: https://github.com/pascme05/TherMOS)
Presenters:
Dr. Pascal Schirmer: received the B.Eng. degree in electrical engineering from the University of Applied Sciences, Esslingen, Germany, in 2018, and the Ph.D. degree in electrical engineering from the University of Hertfordshire, UK, in 2021. Since 2021, he has been working in the R&D department at BMW AG, Munich, Germany, where he is responsible for the lifetime evaluation of power electronic systems. Furthermore, he is a visiting research fellow at the University of Hertfordshire, UK, where he focuses on NILM (software and hardware applications), and a visiting lecturer on electro-mobility at the TAE, Esslingen, Germany.
Dr.-Ing. Peter Schreivogel: received the Dipl.-Ing. degree in aerospace engineering from the Technical University Dresden in 2009, a Research Master from the Von Karman Institute for Fluid Dynamics, Rhode-Saint-Genèse, Belgium, in 2011 and the Ph.D. in aerospace engineering from the University of the Federal Armed Forces Munich in 2015.
From 2015 to 2018, he worked as a thermo-fluid systems engineer at Rolls-Royce Deutschland. Since 2018, he has been a specialist in thermal management of power electronics with the BMW AG, Munich. His research interests include advanced cooling technologies like pulsating heat pipes and reduced order thermal modeling. Dr. Schreivogel was a recipient of the DLR technology award in 2009 and the Claudius Dornier jr. dissertation award in 2016.
