Analysis of AC Resistance of the Ritz Line
Low-cost AC resistance calculation is possible! A solution for AC analysis of Ritz lines.
When an alternating current is applied to a Litz wire, it is known that the resistance increases with higher frequencies due to the skin effect and proximity effect, and this AC resistance can be determined through electromagnetic field analysis. This document introduces examples of calculating the AC resistance of a Litz wire twisted in two stages using EMSolution. By utilizing the periodic symmetry conditions available in EMSolution, it demonstrates that AC resistance calculations using a three-dimensional model of the Litz wire can be performed with low computational costs. **Benefits of calculating AC resistance through electromagnetic analysis:** - Frequency-dependent characteristics of AC resistance can be obtained before prototyping. - The quantitative impact of the number of strands and twist pitch on AC resistance can be understood. - The current distribution within the strands can be visualized. - A deeper understanding of the phenomena can be achieved. *For more details, please refer to the PDF document or feel free to contact us.*
