The transformer is made according to the principle of electromagnetic induction Two windings, a primary winding and a secondary winding, are wound around the closed iron core column When AC power supply voltage is applied to the primary winding There is alternating current in the original Rao group, and the magnetic potential is established. Under the action of the magnetic potential, the alternating main flux is generated in the iron core. The main flux passes through the iron core at the same time, AC link the primary and secondary windings are closed, and the induced electromotive force is generated in the primary and secondary windings respectively due to the action of electromagnetic induction.
This is because the sheet iron core can reduce another iron loss – “eddy current loss”. When the transformer works, there is alternating current in the coil, and the magnetic flux generated by it is of course alternating. This changing magnetic flux produces an induced current in the iron core. The induced current generated in the iron core flows in a ring in a plane perpendicular to the magnetic flux direction, so it is called eddy current. Eddy current losses also heat the core. In order to reduce the eddy current loss, the iron core of the transformer is stacked with silicon steel sheets insulated from each other, so that the eddy current passes through a small section in the narrow and long circuit, so as to increase the resistance on the eddy current path; At the same time, the silicon in silicon steel increases the resistivity of the material and reduces the eddy current. 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.

The annealing temperature of iron-based amorphous alloy is lower than that of silicon steel, and the energy consumption is small, and the iron-based amorphous alloy magnetic core is generally manufactured by special manufacturers. Silicon steel magnetic cores are generally manufactured by transformer manufacturers. According to the above comparison, as long as it reaches a certain production scale, iron-based amorphous alloy will replace some silicon steel markets in electronic transformers within the power frequency range. In the medium frequency range of 400Hz to 10kHz, even if new silicon steel varieties appear, iron-based amorphous alloy will still replace most silicon steel markets with a thickness of less than 0.15mm.
At present, up powder core occupies the main share in the high-end market. However, due to the complex manufacturing process of M, that is, powder core and the noble price of raw materials, the price of powder core remains high and the scope of application is restricted to a certain extent. In recent years, iron-based nanocrystalline soft magnetic powder core has attracted much attention because of its low price, simple preparation process and excellent performance. Its research is quite active, which is expected to replace the local use of up powder core and be applied in the field of high frequency.
