| Abstract |
A new method based on approximating 2D curved field lines by straight field lines with a piece-wiselinear amplitude for calculating the HF-losses in Litz wire caused by a 2D magnetic field in the corewindow is presented in this paper. The error of the proposed method is less than 5\% for the consideredtransformer cases which is much smaller than the typical error of known 1D-field winding loss models(10\%__30\%). The computation time of the proposed method is in the range of a few milliseconds andthus suitable for converter optimization routines. |
