Traditionally, only AC can use electromagnetic coupling to achieve simple and reliable voltage transformation. One of the existing DC voltage transformation schemes is to first invert DC to AC, and then convert to DC after AC voltage transformation. The other is to use a large number of Power electronic devices and components such as large inductance and capacitance are transformed through the coordination of control circuits. Both of these solutions have disadvantages such as complex devices, low conversion efficiency, numerous components, large volume and weight, and high cost. Therefore, the development of a simple structure , small in size and weight, reliable DC transformer parts, especially DC step-up devices have become a key problem to be solved urgently
