Improved analytical modeling of high frequency conductive losses in isolated rectangular conductor

Due to the skin and proximity effect, the conductive losses rectangular conductors under high frequency working conditions increase. And the conventional one-dimensional model, which is currently used for the calculation of rectangular conductor's conductive losses, leads to a considerable error due to the ignorance of edge effect. To eliminate the error, this paper proposes a two-dimensional analytical calculation model based on the electromagnetic theory, which takes the edge effect into consideration, and establishes a new electromagnetic field model to determine the two-dimensional boundary values for the isolated rectangular conductor, and provides a basis for the further improvement of the two-dimensional analytical calculation model. The Finite Element Method (FEM) simulation suggests the proposed model a more effective optimization design method for the isolated rectangular conductor carrying sinusoidal current.
