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...

  How to Purchase High-Quality CMC Common Mode Chokes The quality of the CMC common mode chokes you use determines the quality of the final product. The failure of a low-quality single component will affect the use of the entire product. High-quality components will improve the durability and reliability of the product and will be widely praised by customers. Therefore, when purchasing  common-mode chokes( CMC ) , it is important to put quality at the top of the checklist. SAT Amorphous  has many years of experience in the design and manufacture of common-mode chokes. Whether manufacturing or sales, we put quality first. Based on our many years of experience in the industry, when purchasing any new components, it is not enough to JUST select a supplier. Research and identification are also needed. Check whether the supplier meets the relevant quality standards. Therefore, the following points can be used to evaluate suppliers: 1. Supplier background investigation: Don't j...

  How Common Mode Chokes (CMC) Work Let's study the function and operation of common-mode chokes and how to reduce unnecessary interference. Differential interference First, we study differential interference. For differential interference, and for any signal transmitted from the line side, there should be equal returns on the neutral side. Anything that passes through the neutral point (bottom surface) from the line (or top surface) should be crossed off. But the reality is that if there is equal signal cancellation, you won't get any unnecessary noise in differential mode. Differential noise occurs when these types of transmissions are unbalanced and canceled. Common mode noise In the case of common-mode noise, noise enters and releases simultaneously from the two input sides (line and neutral), but it also couples back to the ground. All that needs to be done is to capture harmful noise and prevent it from spreading back to the ground. Therefore, it is necessary to capture t...
