本文介绍了一种薄而扁平的利兹带状电缆的结构，该电缆适用于电感器和变压器等磁性元件，与传统的实心导体带状导体相比，这些元件需要降低交流损耗。与编织利兹电缆等当前解决方案相比，该导体具有易于制造和低成本的潜力。由于一维分析无法准确模拟带状导体，因此开发了简化的二维分析。测试电感器使用传统的实心铜带状电缆和新型带状利兹电缆构建。将测量结果与一维和二维分析进行比较，结果表明，二维分析提供了更准确的结果。实验结果表明，与类似截面积的实心导体带状电缆相比，新型折叠利兹电缆在相对较宽的频率范围内具有较低的总损耗。
This paper describes the construction of a thin, flat litz ribbon cable suitable for use in magnetic components such as inductors and transformers where one requires reduced AC losses compared to conventional solid conductor ribbon conductors. This conductor has the potential for ease of manufacture and low cost compared to current solutions such as a braided litz cable. Since a 1-D analysis does not accurately model ribbon conductors, a simplified 2-D analysis is developed. Test inductors have been constructed using both a conventional solid copper ribbon cable and the new ribbon litz cable. Measured results are compared to both 1-D and 2-D analyses, and it is shown that the 2-D analysis provides a more accurate result. The experimental results indicate that the new folded litz cable has lower total losses over a relatively wide frequency range compared to the solid conductor ribbon cable of similar cross-sectional area.
