| 摘 要： | 应用有限元仿真软件研究了高频开气隙功率电感器线圈窗口磁场特征及其引起原因.研究结果表明,气隙(磁压)位置对电感器线圈窗口磁场分布有重要影响,进而严重影响线圈涡流损耗.提出通过设计电感器磁压以减小其线圈涡流损耗的设计方法,对一些采用标准化以及非标准化磁芯的高频功率电感器线圈涡流损耗进行了分析与设计,并给出设计准则.有限元仿真验证了该设计方法可以有效、方便地指导减小高频电感器线圈涡流损耗的研究.

| Abstract: | The magnetic field of high-frequency gapped inductor winding window is deeply researched by finite element simulation.The result shows that the gap arrangement has great effect on the field and the AC winding loss.Based on the result,a new method by magneto-motive force(MMF) design consideration is proposed for design and analysis of the AC winding loss reduction.With the method,winding loss of inductors with typical core is analyzed and relative design guidelines are also given.The magnetic field finite element simulations verified the new method effectively. |
