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...

  Amorphous & Nanocrystalline Ribbon Products Available from SAT in 2020 SAT AMORPHOUS  is one of the main manufacturers of iron-based amorphous nanocrystalline cores in China, and an important supplier of nanocrystalline core products from world-renowned groups such as ABB, SE, SMA.  Core products  include toroidal cores, c cut cores, etc. Under the existing production capacity,  SAT AMORPHOUS  provides high-frequency magnetic product designs and competitive soft magnetic core prices. Characteristics The characteristics of the amorphous ribbon are as follows: 1. Amorphous alloy does not have a regular crystal structure like other magnetic materials, and the arrangement of all atoms in amorphous metal is irregular. 2. The resistance value of the amorphous metal is about three times that of crystal. 3. It is prepared by rapidly cooling the melt (about 1,000,000 Celsius degrees per second). This method prevents atoms from arranging into a stable crystal f...
