In today's fast‐paced environment, the downsizing of electronic devices has become imperative. A high driving frequency is effective for the downsizing of electronic equipment. However, one problem with high driving frequency is that it increases the ac resistance and heat generation on passive devices. Using a magnetic coating on the copper wire can effectively reduce the ac resistance. In this study, we propose a method for wrapping a magnetic tape around a copper wire to easily provide a uniform magnetic coating for reducing the ac resistance. In the magnetic field simulation, we reduced the proximity effect in the coil by using a magnetic tape. The temperature rise at the thermal saturation was reduced by 26% for the experiment with a high‐frequency current of 4 A. Applying the magnetic tape to a single‐wire coil effectively reduced the ac resistance and heat generation. © 2020 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

使用磁带减少单线线圈中的交流电阻和发热

在当今快节奏的环境中，必须缩小电子设备的尺寸。高驱动频率对于减小电子设备的尺寸是有效的。然而，高驱动频率的一个问题是，它增加了交流电阻和无源器件上的发热。在铜线上使用磁性涂层可以有效降低交流电阻。在这项研究中，我们提出了一种将磁带缠绕在铜线上的方法，以轻松地提供用于减小交流电阻的均匀磁性涂层。在磁场模拟中，我们使用磁带降低了线圈中的邻近效应。对于4 A的高频电流，该实验在热饱和下的温升降低了26％。将磁带粘贴到单线线圈上可有效降低交流电阻和热量的产生。©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
