How to better know what happens inside a power multi chip module

In this paper, the way to provide an electrical equivalent scheme for any power multi chip module (PMCM) is presented. Considering the geometrical description of the PMCM, an electrical R, L, M circuit is automatically generated using a special software, InCa. This circuit can be used either directly in a PSPICE simulation, or to analyse technical parameters like switching cell inductance, interaction between power and drive circuit or current unbalance in the PMCM.
