Nanocrystalline Cores for Energy Switching

  A choke coil is an inductor designed to have a very big reactance at a determined frequency or frequency range. The common-mode inductor is essentially a two-way filter: on the one hand, it must filter out common-mode electromagnetic interference on the signal line, and on the other hand, it must restrain itself from emitting electromagnetic interference to avoid affecting the normal operation of other electronic devices in the same electromagnetic environment. Choke coils  are widely used in electronic appliances, like television, air conditioner, refrigerator as well as in many other devices by acting as filters. Common mode choke coils are useful in a broad range of precaution of electromagnetic interference (EMI) and radio frequency interference (RFI) of feed lines and for precaution of malfunctioning of several electronic appliances. Additionally, common mode choke coils are also used in circuits like CC-CC converters and load circuits to reduce the noise resulting from...

Amorphous alloy materials   are known for energy saving. Amorphous power transformers have lower core losses than silicon steel transformers, but the magnetostriction coefficient of amorphous alloys is large, which will result in greater core vibration of the amorphous transformer during operation, and the noise level varies The increase. Electromagnetic vibration not only affects the service life of equipment, but also causes more and more attention to the noise environment. Therefore, how to design and manufacture amorphous power transformers with low vibration and noise has become an urgent problem to be solved in its promotion and application. Scientists measured the magnetic properties of the amorphous strip and the amorphous wound core respectively, and obtained the magnetization and magnetostrictive properties of the core under different clamping forces. Based on the measurement data, the magnetic field and stress vibration of the amorphous iron core under different clamping...

6  Applications of Nanocrystalline Inductive Components Nowadays and In The Future Author: Octavius Chung Due to the excellent performance of soft magnetic materials and their unique combination, nanocrystalline materials have become more and more important, mainly reflected in the further improvement of future advanced power electronic systems. Applications such as energy generation and distribution, energy measurement, and management. Compared with the existing conventional soft magnetic materials ,  the use of nanocrystalline cores makes these applications more efficient, reliable, portable, compact, and smart. Nanocrystalline cores and components are playing a more important role in global smart grid projects. 1.  ELCB ELCB was equipped with Permalloy (NiFe) cores many years ago. In recent years, more and more NiFe magnetic cores are being replaced by  nanocrystalline cores . Since the penetration rate has doubled and the volume has been reduced by nearly half, t...
