Abstract:
This paper presents a thermal analysis methodology for modeling the junction-to-fluid thermal resistance of an automotive-grade SiC power module using computational fluid dynamics (CFD) simulations based on manufacturer datasheet data. The resulting thermal resistance map enables accurate electro-thermal simulations across a wide range of operating conditions and geometries, improving predictive capabilities in the design and optimization of electronic power systems.
