要約(英語): This paper introduces a novel method for synthesis of the equivalent circuit of an electromagnetic system described by a homogenized FE equation via model order reduction. The homogenization method replaces fine-structured material such as multi-turn coils, soft magnetic composite and laminated iron sheets with uniform material with complex permeability. The present method reduces the FE equation including the complex permeability to a circuit equation for small variables which can be solved with small computational cost. The present method is effective for time-domain analysis and makes it possible to consider magnetic saturations.
