  • Loss Analysis Using Split Models of Litz Wire

説明

<p>  Litz wire is used to reduce copper loss in high frequency applications. However, it has been confirmed that the loss increases compared with a single wire unless an appropriate Litz wire is selected, and therefore Litz wire cannot be used easily. Loss prediction is necessary to select an appropriate Litz wire, and methods have been reported or solving the Bessel function to make mathematical predictions and methods of making a database from finite element analysis and experiments. Both are effective methods, however complicated modeling or correct reproduction of the usage environment are necessary, and therefore the designer is required to have experience and academic knowledge. The purpose of this study is to enable field engineers to intuitively understand the loss generation mechanism and then handle Litz wire. Therefore, the basic elements of Litz wire were extracted and analyzed with a greatly simplified cylindrical coordinate model to clarify the relationship between the inductive current that causes loss and the wire structure.</p>
