Nanocrystalline Cores for Energy Switching

Tough problems have been solved when ferrite cores were replaced by nanocrystalline soft magnetic cores. (1) Noise In the process of working with electrical appliances, noise is mainly generated in the following two aspects: 1. Due to the magnetostriction index of the raw material itself, such as ferrite, noise always occurs in the application. And because of the different composition of nanocrystalline, the magnetostriction index is also different. For example, as the output transformer, voltage transformer,  common-mode f ilter , etc., the use of iron-based nanocrystalline ribbons reduces the magnetostrictive index. According to customer applications, the noise problem has been greatly improved. 2. The problem at the rectifier circuit level, the direct current in the power supply circuit causes the magnetic induction intensity of the transformer core to increase, thereby causing the noise. Tests have proved that noise is directly proportional to the intensity of magnetic inductio...

The Application of Amorphous Alloy in Sensor Field 2020   Amorphous soft magnetic material   can reduce energy consumption, minimize the noise of electronic circuits of electrical products, and are also environmentally friendly products. Ordinary alloys have a regular metal crystal structure, while the atoms of amorphous alloys are randomly distributed. Due to this random distribution of atoms, the magnetic properties of amorphous alloys are anisotropic. In addition, the increase in resistivity, the amorphous thin ribbon significantly reduces the eddy current loss, so the magnetic properties are significantly improved. In SAT, we have manufactured iron-based amorphous alloys through a liquid rapid cooling method. This method of rapid cooling at a rate of about one million degrees per second can prevent the metal from solidifying into an amorphous structure instead of a normal ordered crystal structure. Due to the advantages of amorphous structure, amorphous alloy has become a ...
