Modeling of Nanocrystalline Hysteresis Properties Considering High-frequency Harmonic Components
摘要
Abstract
Aimed at the problem that the classical dynamic hysteresis model does not take into account the eddy current skin effect,an analytical model of the dynamic hysteresis of soft magnetic materials under high-frequency excitation is proposed based on Maxwell's system of equations.First,the hysteresis relationship between the magnetic flux density and magnetic field strength of materials under high-frequency excitation considering the influence of eddy current skin effect is derived according to Maxwell's system of equations,and an improved prediction method for the eddy current magnetic field strength considering the influence of skin effect is put forward accordingly.Second,the influences of magnetization frequency on the static hysteresis property and anomaly effect of the material are analyzed from a perspec-tive of the corresponding magnetization mechanism,and the modeling methods for static hysteresis and anomalous mag-netic field strength under high-frequency excitation are formulated,respectively.Finally,a predictive model of the dy-namic hysteresis property of nanocrystalline materials under high-frequency excitation is established based on the mag-netic field separation theory,and its validity is verified by a comparison between the measured and simulation results.关键词
