随着高频、高功率密度功率变换器的发展，采用平面化磁芯和印刷电路板（PCB）绕组的电感越来越受欢迎。电感器中的磁通分布受磁芯和绕组的几何形状的影响，进而影响电感器的电感值。提出了pcb绕组平面电感的精确电感计算方法。本文揭示了窗口效应和屏蔽效应，即平面化绕组面积、PCB绕组和工作频率对电感器实际电感的影响。深入分析了条纹效应、窗口效应和屏蔽效应的影响，在此基础上提出了改进的电感计算模型。通过对不同绕组匝数、频率、气隙距离的各种平面电感样品的计算、有限元分析仿真和实验测试，验证了该方法比以往的电感计算方法更精确。
Inductors with planarized magnetic cores and printed circuit board (PCB) windings are becoming more popular with the development of high-frequency, high-power-density power converters. The magnetic flux distribution in an inductor is affected by the geometry of the magnetic core and windings, which in turn affects the inductance value of the inductor. The accurate inductance calculation method is proposed for PCB-winding planarized inductors. The window effect and shielding effect, which can be recognized as the impact of planarized winding area, PCB winding, and operation frequency on the real inductance of an inductor, are revealed in this article. The impact of the fringing effect, window effect, and shielding effect is analyzed in-depth based on which an improved inductance calculation model is proposed. According to the calculation, finite-element analysis simulation, and experimental tests of various planar inductor samples with different winding turns, frequency, and air gap distance, it is verified that the proposed method is more accurate than previous inductance calculation methods.
