摘要：

In this paper, we investigate eddy-current power loss in toroidal cores with a rectangular cross section. Are analytical method is used in which the field variables are. expressed in terms of products of Bessel functions and trigonometric functions. A closed-form expression is derived for the power loss. The influence of various parameters such as skin depth and core dimensions over a wide range is discussed, Simplified expressions far the power loss at special cases such as very small and very large skin depths are provided, A comparison with measured values is presented.
