The Estimation of Power Losses in Composite Cores Excited by Harmonic Flux Density Waveforms
Autor: Mariusz Najgebauer, Damian Gzieł, Jarosław Kalinowski, Branko Koprivica
Publikováno v: Energies, Vol 17, Iss 23, p 5865 (2024)
This paper presents a study of the empirical approach to the estimation of power losses in composite cores excited by harmonic flux density waveforms. Nowadays, magnetic cores operating in power electronic devices are excited by distorted (e.g., harm

Publikováno v: Applied Sciences, Vol 13, Iss 16, p 9134 (2023)
A description of magnetic hysteresis is important for the prediction of losses in soft magnetic materials. In this paper, a viscosity-type equation is used to describe dynamic hysteresis loops in an amorphous ring core for symmetric excitation, as pr

An Improved Approach to Calculate Eddy Current Loss in Soft Magnetic Materials Based on Measured Hysteresis Loops
Autor: Paweł Jabłoński, Mariusz Najgebauer, Michał Bereźnicki
Publikováno v: Energies, Vol 15, Iss 8, p 2869 (2022)
The paper presents a study of the influence of magnetic hysteresis on macroscopic eddy current losses. Usually, this loss is calculated within many simplifying assumptions, of which the most striking is not only neglecting the hysteresis, but also th

Verification of self-similar model of hysteresis loop
Autor: Mariusz Najgebauer
Publikováno v: Publons
The self-similar model of hysteresis is verified for magnetic materials such as electrical steel, amorphous and nanocrystalline alloys. It is demonstrated that this model reproduces only major hysteresis loops, whereas in the case of minor loops –
