Accurate prediction of ferrite core loss with nonsinusoidal waveforms using only Steinmetz parameters
TL;DR: An improved calculation of ferrite core loss for nonsinusoidal waveforms separates a flux trajectory into major and minor loops via a new recursive algorithm that is highly accurate and outperforms two previous methods for measured data.

Calculation of losses in ferro- and ferrimagnetic materials based on the modified Steinmetz equation
TL;DR: In this paper, the influence of nonsinusoidal flux-waveforms on the remagnetization losses in ferro- and ferrimagnetic materials of inductors, transformers and electrical machines used in power electronic applications is discussed.

Improved calculation of core loss with nonsinusoidal waveforms
TL;DR: An extension to the Steinmetz equation is proposed, to enable estimation of hysteresis losses in magnetic core materials with nonsinusoidal flux waveforms, and the new formulation is shown to avoid anomalies present in previous modified-Steinmetz-equation calculations of loss.

A dynamic core loss model for soft ferromagnetic and power ferrite materials in transient finite element analysis
TL;DR: In this article, a dynamic core loss model is proposed to estimate core loss in both soft ferromagnetic and power ferrite materials with arbitrary flux waveforms, where the required parameters are the standard core loss coefficients that are either directly provided by manufacturers or extracted from the loss curve associated with sinusoidal excitation.

Calculation of the Energy Loss in Magnetic Sheet Materials Using a Domain Model
R. H. Pry,C. P. Bean +1 more
TL;DR: In this article, the energy loss resulting from eddy currents was calculated for magnetic sheet materials with a simple domain configuration, and the results were in a form more suitable for quantitative comparison with measured values on materials, such as grain oriented silicon iron, than have been available.

Studies of the Propagation Velocity of a Ferromagnetic Domain Boundary
TL;DR: In this paper, the velocity of propagation of a single domain boundary in a crystal of silicon iron with a simple domain structure is given by a relation of the form $v=G(H\ensuremath{-}{H}_{0})$, where $G$ is a constant and H is the starting field.

Magnetic properties and domain structure in grain-oriented 3% Si-Fe
J. Shilling,G. Houze +1 more
TL;DR: In this article, both static and dynamic domain structures are shown and used to illustrate the relationships among domain structure, metallurgical structure, and magnetic properties, and core losses are shown to depend on the domain wall spacing and mobility, which in turn are controlled by grain size, stress, and defect structure.

Physical interpretation of eddy current losses in ferromagnetic materials. I. Theoretical considerations
TL;DR: In this article, the basic physical mechanism responsible for the general behavior of eddy current losses versus magnetizing frequency fm is recognized in the competition between the external field and local internal fields, due to magnetostatic, coercive, and eddy currents effects.
