In recent years, power electronics devices have been developed to have high frequency and high efficiency, and converters have been developed to have high efficiency and high reliability, and to have been miniaturized. Among them, the reactor is an important component in the converter. Therefore, how to improve the efficiency and temperature rise of the reactor in a high-frequency environment without increasing the volume of the reactor, that is, how to apply the reactor in a high-frequency environment, has become an important research direction. The soft magnetic material reactor adopts a special iron core material such as iron silicon, iron silicon aluminum, ferrite, iron powder core and the like, and the efficiency and the temperature rise of the whole reactor are in an allowable range because the loss of the soft magnetic material reactor in a high-frequency environment is low.

When the winding is wound on the iron core, the winding is controlled by the pulling direction of a winding person, and in the process, the winding has certain rigidity, so that the winding effect is influenced due to the fact that the winding is easy to shift in position on the iron core.
