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.

Now, the test of magnetic core material loss of power frequency power transformer is carried out under sine wave voltage with distortion less than 2%. The actual power frequency power grid distortion is 5%. In this case, the loss of iron-based amorphous alloy increases to 106% and that of silicon steel increases to 123%. If the high-order harmonic is large and the distortion is 75% (such as power frequency rectifier transformer), the loss of iron-based amorphous alloy increases to 160% and the loss of silicon steel increases to more than 300%.

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”. Nanocrystalline magnetic core is a small part with magnetic conductivity. There are nanocrystalline particles with small particles in the center of nanocrystalline magnetic core. The working principle of nanocrystalline magnetic core is to absorb the common mode current in the cable through the principle of induction heating and convert it into heat to dissipate. rolled silicon steel sheet is selected. It is cut into long pieces according to the size of the required iron core, and then overlapped into “day” shape or “mouth” shape. In principle, in order to reduce eddy current, the thinner the silicon steel sheet, the narrower the spliced strip, and the better the effect. This not only reduces the eddy current loss and temperature rise, but also saves the material of silicon steel sheet. But in fact, when making silicon steel sheet iron core. Not only from the above favorable factors, because making the iron core in that way will greatly increase the working hours and reduce the effective section of the iron core. Therefore, when making transformer iron core with silicon steel sheet, we should start from the specific situation, weigh the advantages and disadvantages and choose the best size.

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.
