高频功率变换器中电磁元件趋于平面的趋势给工作频率在兆赫兹范围内的电感器的设计带来了困难。研究了现有和改进的两种电感设计概念，并分析了它们对内外漏场的影响。给出了磁通图来说明这些磁场的模式，并给出了绕组损耗的理论和实验结果
The trend towards planar shapes for electromagnetic components in high-frequency power converters presents difficulties for the design of inductors that operate at frequencies in the megahertz range. Two existing and two improved inductor design concepts are studied, and it is shown how the internal and external leakage fields are affected by them. Flux plots are presented to illustrate the patterns of these fields and theoretical and experimental results for winding losses are given.<<ETX>>
