摘要
研究了部分填充矩形截面环形磁芯中的磁场 ,给出了填充材料边界处的条件 ,得到了涡流产生的磁场强度 HΦ 关于贝塞尔函数和三角基函数的双重级数的解析解 ,并计算了涡流损耗。
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.
