Paper title: EFFECT OF CURRENT HARMONICS ON THE HYSTERESIS LOSSES IN SOFT MAGNETIC MATERIALS
Author(s): VALENTIN IONIŢĂ, LUCIAN PETRESCU, EMIL CAZACU,
Abstract: The paper presents an efficient numerical procedure, which estimates the hysteresis
losses in the FeSi materials, for periodic nonsinusoidal magnetic field having the harmonic
spectrum revealed by industrial measurements made for transformers supplying various
consumers. The used hysteresis model is a scalar classical Preisach model, its statistical
distribution function being identified from the symmetrical cycles, measured by an industrial
equipment – a single sheet tester (SST). The numerical procedure is adapted to the soft
magnetic material, by using a nonuniform meshing of Preisach triangle.
