Abstract

It is well known that the skin effect occurs at high frequency excitation, and the lamination of the steel sheets will affect on the distribution of the eddy current. In this paper, laminated core and wound core type toroidal reactor is calculated using the 3-D finite element method. The effect of the lamination of the steel sheets at high frequency excitation is clarified quantitatively.
