Simulation of hybrid power components: a new electrothermal model

An electrothermal model for simulating the thermal behavior of hybrid power components is presented. This model consists of an electrical empirical model and a thermal model which uses the finite-element method for the calculation of temperature distribution in the component structure. The procedure for applying this model to a power component under steady-state conditions (during commutation and conduction) is explained, and the results of simulation for a typical hybrid power component, an insulated-gate bipolar transistor, at steady-state forward conduction are presented. The experimental measurements for different power modules show good agreement between the simulated and the experimental characteristics.<
