摘要：

Magnetoplated wires (MPW) are effective to reduce eddy current losses in power devices such as converters and contactless power transfer systems. In the convenient finite element (FE) analysis of MPW, elements must be sufficiently smaller than the skin depth. This results in large number of unknowns. This paper proposes a homogenization method using complex permeability for FE analysis of MP-coils so as to circumvent this problem. The coil impedances obtained by the proposed method with coarse elements are shown to agree well with those computed in the conventional FE analysis with fine elements. © 2017 The Institute of Electrical Engineers of Japan.
