MoM and PEEC Method to Reach a Complete Equivalent Circuit of a Static Converter

Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Electromagnetic simulation of power modules via adapted modelling tools

“…In order to expand the frequency range of the (R, L) PEEC circuit, it is also possible to include parasitic capacitances computed by a dedicated integral method [6] or by the Adaptive Multi-Level Fast Multipole Method (AMLFMM).…”

“…Meanwhile, the equivalent capacitances representing the electric couplings between the conductors are computed by means of the AMLFMM algorithm [6], which is also able to take into account the influence of the PCB dielectric substrate.…”

Volume Integral Formulation Using Face Elements for Electromagnetic Problem Considering Conductors and Dielectrics

“…A few previous publications have considered dielectric materials [18], [19], which have limitations. For instance, in [19] the magneto-quasi-static and electrostatic problems are solved separately, so the phenomena are not strongly coupled. Moreover, the user has to define macroelements manually (which are a group of elements of the mesh) for the electrostatic solution, which may add some inaccuracy to the electrical phenomena.…”

“…In practice, the PEEC method is mostly used to model conductors and resistive, inductive and capacitive effects [14]- [16]. A few previous publications have considered dielectric materials [18], [19], which have limitations. For instance, in [19] the magneto-quasi-static and electrostatic problems are solved separately, so the phenomena are not strongly coupled.…”

Impact of SiC components on the EMC behaviour of a power electronics converter

“…This formula appreciates edge effects. Since the stray capacitances between tracks have been found negligible compared to the capacitances between tracks and ground plan [8], only four stray capacitances have been integrated to the Saber® model. Finally the presented method (simulation in InCa3D® for the inductive effects and the Sakurai Tamaru formula for the capacitive effects) allows the predicted parasitic effects of the routing without construction of a prototype.…”
