【Abstract】 A numerical formulation and corresponding FEM algorithm for eddy current analysis of solenoidal coils considering skin effect and proximity effect in high frequency conditions are presented in this paper. The formulation and algorithm solve the important problem of how to impose the constrained conditions that the total currents in every turn of coils must be the same. And practical calculations and analyses are successfully performed for the high frequency parameters of air core coils, such as the resistance and inductance of solenoidal inductors.更多还原
