Abstract
A parameter identification of the Jiles-Atherton hysteresis model for a sof t magnetic composite (SMC) is realized directly by a nonlinear optimization technique coupled with a 2D field calculation. The identification method f its experimental instantaneous voltage and current measurements realized on a transformer with a cylindrical symmetry, made of a soft magnetic composi te material. The method is integrated in a global CAD environment for the o ptimal design of SMC transformers and used to take account of technical con straints related to the production and assembly of SMC transformers.
