Problems solved by technology

If the output voltage is increased by increasing the number of turns of the secondary coil, a larger magnetic core needs to be designed for supporting, not only the design process is complicated, but also the production is more difficult, and the product performance is not good; if the magnetic core with a higher power level is selected To increase the output power, it is necessary to screen the magnetic materials, and different output powers correspond to magnetic materials of different power levels. When the transformer is used in various occasions, it must be equipped with magnetic materials with special structures. Therefore, the waste of raw materials is serious. , and the transformation of magnetic materials can easily lead to poor performance
