A Physical RC Network Model for Electrothermal Analysis of a Multichip SiC Power Module

This paper is concerned with the thermal models which can physically reflect the heat-flow paths in a lightweight three-phase half-bridge two-level SiC power module with six MOSFETs and can be used for coupled electrothermal simulation. The finite-element (FE) model was first evaluated and calibrated to provide the raw data for establishing the physical resistor-capacitor (RC) network model. It wa...
