Magnetic components are essential power electronic devices used for energy storage, energy conversion, and electrical isolation. They mainly include transformers and inductors. These components are composed of magnetic cores and windings, where the windings are generally made of copper enameled wires, and the magnetic cores are typically made of soft magnetic materials such as magnetic powder cores, ferrites, or amorphous nanocrystals. When purchasing magnetic components, it is necessary to comprehensively consider the cost, volume, weight, and performance index requirements of the system. Components that cannot be sourced from the market must be specially designed.
