Thermal Characterization of Automotive Power Modules with an Embeddable BCI-ROM

This paper introduces a novel thermal characterization approach for automotive power modules with an embeddable boundary condition independent reduces-order model (BCI-ROM) technology. The thermal transient measurement method, thermal simulation modeling, its calibration procedures, and an embeddable BCI-ROM are employed in this study. This model represents a significant enhancement to the exchange of package models within the automotive supply chain. The results of the BCI-ROM are in high agreement with the detailed Flotherm thermal model. Furthermore, an embeddable BCI-ROM is developed for automotive drive cycles, which are obtained from a calibrated thermal model.
