High-Frequency Copper Losses in Magnetic Components With Layered Windings

  title={High-Frequency Copper Losses in Magnetic Components With Layered Windings},
  author={G. Dimitrakakis and E. C. Tatakis},
  journal={IEEE Transactions on Magnetics},
Copper losses in magnetic coils depend on several geometrical parameters, as well as on frequency, in a way that makes their analytical modeling a quite difficult task. In this paper, we describe how we use a finite-element-analysis software to investigate a series of issues critical to the accurate determination of high-frequency copper losses in layered coils. Some of the issues we investigate are the impact of the edge effect and the winding pitch on the overall copper losses. We examine the… CONTINUE READING
