Soft magnetic materials are those materials that are easily magnetised and demagnetised. They typically have intrinsic coercivity less than 1000 Am-1. They are used primarily to enhance and/or channel the flux produced by an electric current. The main parameter, often used as a figure of merit for soft magnetic materials, is the relative permeability (µr, where µr = B/ µoH), which is a measure of how readily the material responds to the applied magnetic field. The other main parameters of interest are the coercivity, the saturation magnetisation and the electrical conductivity.
We know that the actual transformer always works in AC state, and the power loss is not only on the resistance of the coil, but also in the iron core magnetized by alternating current. Usually, the power loss in the iron core is called “iron loss”. The iron loss is caused by two reasons, one is “hysteresis loss” and the other is “eddy current loss”. Hysteresis loss is the iron loss caused by the hysteresis phenomenon in the magnetization process of the iron core. The size of this loss is directly proportional to the area surrounded by the hysteresis loop of the material. The hysteresis loop of silicon steel is narrow, and the hysteresis loss of transformer core made of silicon steel is small, which can greatly reduce its heating degree.
The common mode inductor using nanocrystalline core material can well suppress the peak voltage, protect sensitive components, and reduce the motor shaft voltage. Because of the unique characteristics of nanocrystalline core, it has been well used in some high-power system industries. Electric energy meter, power meter, ammeter, electric measuring equipment and other instrument fields. Various power current transformers in power transmission and distribution monitoring system. Leakage protection, relay protection, servo motor protection, fire monitoring, etc Current and voltage data sampling, etc.

Amorphous nanocrystalline alloys are competing with soft ferrite in the field of medium and high frequency. In 10kHz to 50KHz electronic transformer, the working magnetic flux density of iron-based nanocrystalline alloy can reach 0.5T and the loss P0.05 5 / 20K ≤ 25W / kg, so it has obvious advantages in high-power electronic transformer. In 50 kHz to 100 kHz electronic transformer, the loss of iron-based nanocrystalline alloy is P0.05 2 / 100k is 30 ~ 75W / kg, Fe based amorphous alloy P0.05 2 / 100k is 30W / kg, which can replace some ferrite markets.
Application field of nano magnetic core: Noise is the main circuit interference source in many power electronic devices. Various filter elements must be used to reduce noise. As the main component of differential mode inductance, magnetic particle core plays a key role in the filter. In order to obtain better filtering effect, the magnetic particle core material is required to have the following performance characteristics: high saturated magnetic induction, wide constant magnetic conductivity, good frequency characteristics, good AC / DC superposition characteristics and low loss characteristics. According to the above requirements, soft magnetic materials for inductance such as iron powder core, notched amorphous alloy core and iron nickel aluminum powder core (MPP powder core) have been developed successively. These materials have played their respective advantages and roles under different application conditions.
