Fractal Structure of the Core Loss Spectrum of Co-based Amorphous Soft Magnetic Alloy with Constant Permeability

摘要: In order to check the traditional core loss formula, the core loss spectrum P(f) of Co-based amorphous soft magnetic alloy with constant permeability has been studied. It is found that within a high frequency range from 10 kHz to 200 kHz and at Bm = 0.1 T,the P(f) has the fractal structure P(f) = P0fD, and with the increasing of induced anisotropy energy Ku, the fractal dimension Dt rises, thus the total power loss at high frequency increases and the frequency characteristic of P(f) becomes worse.
