Eddy Current Analysis of Three-Phase Transformer Made of Grain-Oriented Electrical Steel Sheets Using 3-D Parallel FEM

摘要

We analyzed a three-phase transformer made of laminated grain-oriented electrical steel sheets using the three-dimensional parallel finite element method. The magnetic flux and eddy current distribution of the transformer are clarified in detail. Moreover, it is clarified that the eddy current loss of the transformer is affected by the build-up method of the laminated electrical steel sheets.
