Problems solved by technology

[0004] Electromagnetic power components are realized by discrete components, not only the number of components is large, but also the shapes and sizes are different, and the space utilization rate is low. The use of discrete components greatly reduces the power density of power electronic circuits, and even the parasitic parameters of discrete components, such as the inductance The equivalent parallel capacitance, the pin inductance of the capacitor and the wiring layout can also adversely affect the performance of the LCC resonant converter circuit
