A Numerical Method for Calcuating High Frequency Reluctance of Coils

摘要

A numeric formulations and corresponding FEM method for calculating the relutance of solenoidal coils considering the skin effect and proximity effect in high frequency conditions are presented in this paper. This method solves the improtant problems of how to impose the constrained conditions that the total currents in nvvery trun of coils must be the same. And practical calucations and analyses are successfully performed for the high frequency parameters of air-core coils, such as the resistance and inductance of solenoidal inductors.
