The extended finite element method (XFEM) is utilized for high-frequency eddy current analysis. However, when a conductor with a curved surface is involved, the geometric approximation tends to degrade due to the coarse mesh used in XFEM. To enhance the approximation accuracy, exact boundary representation (EBR) methods are employed within XFEM for eddy current analysis. The proposed method is validated using a round conductor model, demonstrating a substantial reduction of error in global quantities such as Joule losses compared to conventional methods.
