Accuracy and boundary condition independence of Cauer RC ladder compact thermal models
This paper presents an experimental study aimed at the investigation of the influence of variable boundary conditions on the element values of compact thermal models. These models are generated from the time constant spectra of thermal responses in the form Cauer RC ladders in such a way that their individual components might have some physical interpretation and correspond to individual stages in the heat flow path. The accuracy of thermal simulation results obtained using the proposed models is validated with temperature measurements of discrete silicon carbide power devices.
