Abstract
In the reliability evaluation of power electronic systems, one of the challenges is to model the thermal profiles across multiple time scales, i.e., from switching cycles at nano- or micro-seconds to annual or even longer-time mission profiles. Without consideration of the dissimilarity of thermal behaviors under different time scales, a single thermal model usually leads to either considerable modeling errors or heavy computational burden. Based on the frequency response of thermal impedances, this paper proposes a novel and simplified thermal model to analyze mission profiles with multiple time scales. It enables a computational-efficient thermal stress analysis for power semiconductors, including the thermal coupling in device packages. The theoretical results are verified by experimental testing.
