Inverter interference how to choose the magnetic ring

Now we share with you a little common sense about Kexiang inverter interference magnetic ring. ☆ Inverter interference magnetic ring is lossy filter, mainly used to suppress the conduction interference on the cable. Mainly used in computers, local area networks, communications, office automation equipment, various types of household appliances, lighting appliances and other data lines field. ◆ Inverter interference magnetic ring, also known as ferrite magnetic ring, referred to as magnetic ring, it is a commonly used anti-interference components in electronic circuits, for high-frequency noise has a good suppression effect. ☆ Electronic equipment radiation and leakage of electromagnetic waves not only seriously interfere with the normal work of other electronic equipment, resulting in equipment dysfunction, transmission errors, but also threaten the health and safety of human beings, the harm is very great, so reduce the electromagnetic interference of electronic equipment (EMI) has been a must consider the issue. ◆Frequency inverter interference magnetic ring selection, the main consideration of two factors: the impedance characteristics of the ring and the interference characteristics of the filtered circuit, the appearance of the preferred choice of "as long as possible, as thick as possible, as small as possible inner diameter, inductance as small as possible" of the magnetic ring. The biggest advantage of using inverter interference magnetic ring is that there is no electrical connection with the filtered circuit; the biggest disadvantage is that the magnetic ring is fragile, so it is recommended to use a magnetic ring with a plastic shell and fix it on the filtered power line or control cable. In addition, after passing through the magnetic ring, the filtered power line or control cable can be wound around the magnetic ring several times repeatedly, which can increase the cable's inductance, and it will have a better effect of interference suppression. ◆ Inverter interference magnetic ring according to the frequency characteristics of the interference signal can be selected nickel-zinc ferrite or manganese-zinc ferrite, the former high-frequency characteristics are better than the latter, manganese-zinc ferrite permeability in a few thousand - tens of thousands, and nickel-zinc ferrite for a few hundred - thousands of the higher the permeability of the magnetic ring ferrite, the greater the impedance of its low-frequency, high-frequency impedance is smaller, so in the inhibition of high-frequency interference, it is desirable to use nickel-zinc Therefore, when suppressing high-frequency interference, it is better to use nickel-zinc ferrite, on the contrary, use manganese-zinc ferrite, or in the same bunch of cables at the same time on the set of manganese-zinc and nickel-zinc ferrite, so that the interference band can be suppressed is wider. ◆Inverter interference magnetic ring products are sold to all over the country, especially Beijing, Shanghai, Tianjin, Chongqing, Hebei, Shanxi, Taiyuan, Inner Mongolia, Liaoning, Shenyang, Dalian, Jilin, Heilongjiang, Harbin, Shandong, Jinan, Qingdao, Jiangsu, Nanjing, Huaian, Yancheng, Taizhou, Lianyungang, Suqian, Zhenjiang, Suzhou, Wuxi, Nantong, Yangzhou, Xuzhou, Huaiyang, Changzhou, Anhui, Hefei, Chuzhou, Huainan, Zhejiang, Wenzhou, Jinhua, Jiangsu, Zhejiang Province, China.
