Abstract
The aim of the study is to develop some nodal models describing thermoechanical link in power devices. It is focused on modelling, simulating and testing a component: the silicone gel used in power electronics modules. Due to the future availability of high temperature gel, this study is a first step to establish a multiphysic model. The study aims to establish fast and compact electro-thermomechanical model than can be connected to circuit models, representing other packaging components. In first stage, a finite element model of a commercial gel is defined and some simulation results are presented. In a second stage, an equivalent “electrical” compact model is also suggested and compared to measurements and 3D simulation results. The results presented concern temperature dispatching in both, simulations and measurements, and averaged stresses as well as displacement within the silicone. Future works will describe the thermomechanical link in nodal models, as well as real environment surrounding the silicone gel. Indeed, the silicone thermal expansion impact will be monitored.
