Error Evaluation of Surface Impedance Boundary Conditions with Magnetic Vector Potential Formulation on a Cylindrical Test Problem

摘要

Surface Impedance Boundary Conditions (SIBC) are used for analysis of a wide range of practical applications such as micro strips, transformers or electrical machines. In this work the SIBC are implemented with classical edge elements using the magnetic vector potential A. The radius of the conducting and permeable cylinder was varied from 0.05 m to 0.01 m. Simulation results with the SIBC formulation are compared with the common A,V-Φ formulation for eddy current regions. Results are presented and discussed by means of a canonical problem.
