Dual magnetodynamic formulations and their source fields associated with massive and stranded inductors

摘要

The treatment of massive and stranded inductors is studied in the frame of dual magnetodynamic finite element h- and /spl alpha/-formulations. On both sides, edge finite elements are used and source fields are defined when needed as mathematical tools to be used directly in each formulation to lead to circuit relations for inductors. Simplified expressions of source fields are proposed. The accuracy obtained on local solutions and circuit parameters is pointed out.
