Abstract

Real-time health management of power electronic devices is emerging as a key tool in the drive for cost, weight and volume in achieving efficient systems with high reliability and performance. Implementation of such schemes requires real-time electro-thermal models that can be used to predict the temperatures of device junctions, interfaces etc. that cannot ordinarily be measured during service. This paper presents a real-time reduced-order thermal model that includes a multi-rate computational method to improve efficiency. Results from the developed reduced-order model are presented along with experimental measurements that validate the model. The model is used as a tool to investigate the effects of module temperature variations for health management purposes.
