Scaling in Modeling of Core Losses in Soft Magnetic Materials Exposed to Nonsinusoidal Flux Waveforms and DC Bias

摘要

Assuming that core loss data of Soft Magnetic Materials obey scalingrelations, models describing the power losses in materials exposed tonon-sinusoidal flux waveforms and DC Bias conditions have been derived. Inorder to test these models, the measurement data for two materials have beencollected and the core losses calculated. Agreement between the experimentaldata and the model predictions is satisfactory.
