N2 - An analytical model based on one dimensional 1-D Dowell's equation for computing actodc resistance ratio FR of litz wire is presented. The model describes three frequency ranges: lowfrequency range, medium-frequency range, and highfrequency range. In each of the ranges, the behavior of ac-to-dc winding resistance ratio FR is different. Moreover, the boundary frequency between the lowfrequency and the medium-frequency ranges, are given for both round solid wire and litz wire inductors. Hence, useful frequency range of both wires can be determined. Comparison of the ac-to-dc winding resistances ratio FR for solid and litz wires is presented.
