高频多谐波激励下计及趋肤效应的软磁带材磁滞及损耗特性预测
Predicting Hysteresis and Loss Characteristics of Soft Magnetic Tape Material Considering Skin Effect Under High Frequency Multi-harmonic Magnetization
摘要
Abstract
The nonlinear magnetization characteristic of soft magnetic materials makes it difficult to analyze the distribution of eddy currents and their loss characteristics in soft magnetic tape materials.Therefore,a piecewise linear method is used to approximate the basic magnetization curve.Based on the derivation of Maxwell's equations in each linear segment,the expression of the average magnetic field intensity Hcl corresponding to eddy current loss in soft magnetic tape materials under single-frequency sinusoidal magnetization is obtained,and the corresponding parameter identification method is proposed.Furthermore,based on the consistency principle of field separation technology and loss separation,a high-frequency dynamic hysteresis model in the form of field separation is established.In accordance with the high-order harmonic characteristics in practical applications,a calculation method for the magnetic field intensity Hcl corresponding to eddy current loss under multi-harmonic excitation is constructed based on the approximate linear characteristics of permeability and the superposition principle of field quantity,and a dynamic hysteresis prediction model for soft magnetic tape materials under complex multi-harmonic magnetization is further proposed.The effectiveness and accuracy of the method proposed in this paper are verified by comparing experimental results with simulation results.关键词
