To enable the design and analysis of Integrated Power Electronics Models (IPEMs), a high level of software integration is needed. The solvers needed range form electrical circuit simulators, like Saber, to thermal analysis and CFD solvers like I-DEAS. As an electrical design parameter is changed, its effect will, in principle, be felt all the way to the temperature distribution in the cooling fluid, and hence a complete solution of the temperature field may have to be recomputed. This is of course computationally prohibitive. Hence a reduced-order model of the thermal behavior of the heat sink is of great interest. In this paper, we will present an algorithm that can automatically generate these reduced-order models from finite-element simulations.
