Non-intrusive electro-thermo-mechanical reduced model for diagnosis and prognostic on IGBT power modules

Résumé

In this work, a reduced model based on the Proper Generalized Decomposition is developed to model the electro-thermo-mechanical of IGBT power module. The reduced model enables obtaining the solution to the coupled problem considering multiple model parameters. Focusing on the wire bond lift-off mechanism, a lifetime model is built based on the stress level at the wire bond metallization interface. The reduced model is then advantageously used to perform model updating using Bayesian inference.
