Inhalt:
To ensure high performance of power modules, the parasitic behavior is often estimated by the state-of-the-art software ANSYS Q3D Extractor. Nevertheless, previous papers showed significantly high deviations between Q3D-simulations and impedance analyzer based measurements. However, impedance analyzers tend to lose accuracy for small inductances, and inductive couplings are often not taken into consideration. In this paper, a measurement-setup for self- and mutual inductances of power modules is introduced and compared to simulations using ANSYS Q3D Extractor. As a result, it is shown that the simulative deviation is lower than 15%. Further setup-modification might lead to even higher consistency.
