Efficient Simulation of Magnetic Components Using the MagPEEC-Method
TLDR
A quasi-static formulation of the PEEC-method including inductive and capacitive effects is coupled with a surface magnetization formulation allowing for modeling linear magnetic materials in combination with arbitrary conductor arrangements.Abstract:
In this paper, a quasi-static formulation of the PEEC-method including inductive and capacitive effects is coupled with a surface magnetization formulation allowing for modeling linear magnetic materials in combination with arbitrary conductor arrangements. Special care is taken to give a systematic derivation of the underlying equations, an adaptive mesh algorithm for the surface mesh of the magnetic materials, and a multifunction implementation for a mixed domain concerning orthogonal and nonorthogonal cells. The approach is verified with examples according to the finite-element method and measurements.read more
