The Computation of 3-D Eddy Current and the Additional Losses in the Nonlinear ASnisotropic and Thin Skin Depth Materials

摘要

In this paper, a well-improved 3-D nonlinear and anisotropic computing model is set up. The modified nonlinear Impedance Boundary COnditions(IBC) is used on the surface of the thin skin depth conductors to eliminate this conductor our of the sloving region. The verification model~(3) is used to examine the computing model proposed. A BKS-20000/66 type iron core reactor is also computed by the methods mentioned in the paper.
