switching power supply with a nanocrystalline magnetic alloy Fe74Cu1Nb1Mo2Si13B9
 
In particular, the transverse magnetic field on the level reached after the annealing,uggs outlet, the new alloy shows a more pronounced effect of magnetic field annealing. 3.2 AC frequency effective permeability of Table 2 shows the relationship between the different frequencies up to 1MHz FCII. M0i. Alloy relative effective permeability of the value, and with FNbi. The corresponding values ​​were compared. It can be seen. Permeability of the new alloy dispersion characteristics table 2FcNblM and Nb ~ SiI of effective permeability versus frequency Ku touch 2Effec ~ mag, e ~ ~ pmmmty a mm Yo F № lMI! B · a s song. & Hill of better than, C ~ Nb, SiI Mary difference. 3.3 Figure 1 shows the high-frequency iron loss of the new alloy in f = 2o ~ 1000kHz range of amplitudes corresponding to different high-frequency magnetic flux density Lei iron loss. P and can be seen, the existence of several very good linear correlation to ask. Measurements showed that the number of P and the wind on Ke also have a fairly good linear relationship. Figure 2 shows the corresponding product or = 10. 15,abercrombie fitch,20,30 (× l · Hz) of the iron loss frequency relationship. P and can be seen,ralph lauren danmark, the logarithm is a linear relationship, although the larger crystal, in the f - 20 ~ 30kEk range of memory in less than 4% of the linear relationship with the relative deviation. As an example, Figure 2 is also expressed in the corresponding wind f - 15x10T · Hz corresponding frequency amplitude permeability relationship, we can see p. And, also on the number of linear association. In the wind f = (10 ~ 30) × IOT · Hz range, the corresponding. Less,abercrombie fitch hamburg, it is. , The basic weight curve left.
