A comparison of nodal- and mesh-based magnetic equivalent circuit models / Derbas, Hamza W. in IEEE transactions on energy conversion, Vol. 24 N° 2 (Juin 2009) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 24 N° 2 (Juin 2009) . - pp. 388 - 396 Titre : A comparison of nodal- and mesh-based magnetic equivalent circuit models Type de document : texte imprimé Auteurs : Derbas, Hamza W., Auteur ; Williams, Joshua M., Auteur ; Koenig, Andreas C., Auteur Année de publication : 2009 Article en page(s) : pp. 388 - 396 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Newton-Raphson  method;  equivalent  circuits;  machine  theory;  magnetic  circuits Résumé : The magnetic equivalent circuit (MEC) technique is a powerful analysis and design tool that combines relative accuracy with moderate computational effort. In this paper, a nodal-based MEC formulation and a mesh-based MEC formulation of a magnetic system are compared. The Newton-Raphson algorithm is used to solve the algebraic system, and to draw conclusions about the computational efficiency of the two formulations under linear and nonlinear operation. Although the two formulations exhibit similar performance under linear operating conditions, the performance of the mesh-based model is significantly better than that of the nodal-based model under nonlinear operation.
