Accurate analytical model of winding losses in round Litz wire windings
Abstract
An accurate analytical model of losses in round Litz wire windings is presented. The model is based on the exact analytical equations for round conductors, and it closely includes the distribution of the leakage field across the winding space. A closed-form formula of the ac resistance of round Litz wire windings is developed from the model. An analytic solution of the optimal value of the ac resistance is derived. The expression of the strand dimension corresponding to the optimal value of the ac resistance is also determined.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
