N2 - A new accurate internal temperature prediction model of T-type inverter module is proposed, considering the electro-thermal coupling effect and the correction of the boundary conditions in the finite element analysis. With high accuracy and reliability, it has a good application prospect using to study the influence of multiple physical fields on the junction temperature in actual operation. In this paper, power loss analysis is first presented based on the T-type power module topology. Then the steady-state and dynamic prediction models of the junction temperature is demonstrated based on the finite-element method (FEM) and the Cauer and Foster thermal-impedance, respectively. Finally, simulation results are provided to verify the accuracy of temperature prediction of the two thermal models.
