Abstract :
Nanocrystalline soft magnetic materials combine low magnetic losses with high permeability and high saturation induction. Those properties are useful for power electronics. The linear behaviour below saturation allows superposition of losses in the frequency domain. The losses of three toroidal Vitroperm 500 F cores are investigated under square voltage.
