Application of Scaling Algorithms in the Analysis of Energy Losses Under Non-sinusoidal Excitations

The paper presents the measurements of the hysteresis loops and energy losses in a nanocrystalline composite core, obtained for sinusoidal and triangular waveforms of magnetic flux density. The influence of flux density waveforms on the shapes of hysteresis loops and energy losses, as well as the corresponding coefficients in the scaling-based loss model, are investigated. The scaling-based modelling of energy losses is validated for both types of the analysed flux density waveforms.
