摘要 为了减小磁性元件的绕组损耗,Litz线备受设计者们的关注,但其庞大的单线股数和复杂的绞制方式使得Litz线的绕组损耗难以计算和仿真。本文从Litz线的绞制方式出发,分析不同绞制方式下Litz线的电流分配特性,并针对业界更普遍使用的同心绞Litz线进行细致分析,提出分段并绕平行线可近似替代同心绞Litz线的想法,并以此为依据使用分段等效电路法求解同心绞Litz线的单线电流,然后将求得的单线电流值重新赋值到2D并绕平行线的仿真模型中进行仿真,即可求解同心绞Litz线的绕组损耗,并在最后验证了分段等效电路法求解同心绞Litz线绕组损耗的有效性和准确性。

Abstract:In order to reduce the winding losses of magnetic components, Litz wires brought designers into sharp focus. But its large strands and complex twisting mode makes the winding loss of Litz wires difficult to calculate and simulate. This paper from twisting mode to analysis the current assignment characteristics of different twisting mode of Litz wires, and particularly analysis the concentric twisted Litz wires which is more widespread used in the industry. The thought is proposed that concentric twisted Litz wires can be approximately replaced by segmented stranded parallel wires, and the single wire current of concentric twisted Litz wires can be solved by using the segmented equivalent circuit method based on this thought. Reassignment the single wire current value to 2D stranded parallel wires model for simulation, and then the winding loss of concentric twisted Litz wires can be solved. Finally, it is proved that the segmented equivalent circuit method is effective and accurate for solving the concentric twisted Litz wire winding losses.
