【Abstract】 In this paper, we investigate the magnetic field in partly stuffed toroidal cores with rectangular cross. Boundary conditions along the stuffing are provided. Thus, analytical solution of the magnetic field H Φ  which is expressed in terms of products of Bessel functions and trigonometric functions is obtained. The final solution of power loss is also derived.更多还原
