摘　　要：准确、快速计算高频磁性元件圆形利兹线绕组损耗对高频变压器、高频电感器等现代电工装备的优化设计及其电磁综合性能提升等具有重要意义。然而,现有唯一专门应用于高频磁性元件圆形利兹线绕组损耗计算的解析模型存在推导失误、不准确等问题。为此,该文首次指出其推导过程中的错误点,并推导相应正确的公式,从而得到准确通用的高频磁性元件圆形利兹线绕组损耗解析预测模型。最后,将仿真与实验结果对比,验证所提模型的准确性与实用性。Accurately and quickly estimating losses of the round Litz wire of high frequency magnetic components is very crucial for the optimal design of the high frequency transformers,high frequency inductors and other modern electrical equipment,and for their overall electromagnetic performance improvement,etc.However,the only existing analytical model that is specifically developed for the loss prediction of the round Litz wire winding of high frequency magnetic components has some drawbacks,such as the derivation mistakes.This paper points out the wrong points in the derivation process of this analytical model for the first time,and thereby correspondingly deduces the correct formulae.Consequently,an accurate and general analytical model for the round Litz wire winding loss calculation of high frequency magnetic components is derived.Finally,the simulation and experimental results are compared to verify the accuracy and practicability of the proposed analytical model.
