Appropriate modelling of conductive losses in the design of magnetic components

An analytical method to calculate the AC resistance of round conductor windings is derived. It is shown that the skin effect and proximity effect are orthogonal to each other, which means that their losses can be calculated separately and then simply added together. It is shown that this method of calculation is inherently much more accurate than a popular existing method using an equivalent rectangular conductor and a one-dimensional cartesian coordinate system solution.<<ETX>>
