Problems solved by technology

[0003] At present, the core issue that limits the large-scale application of wireless charging lies in the efficiency of power conversion, because in the process of wireless charging, the rectification of AC to DC and the inversion of DC to AC are required, as well as the need for transmission through electromagnetic waves. These processes will inevitably cause energy loss, especially to achieve long-distance high-power wireless magnetoelectric conversion, so the energy consumption of the equipment is relatively high
As the distance and power of wireless charging equipment increase, the consumption of useless work will also increase; at present, the energy conversion rate is less than 50% for a transmission distance greater than 50cm;
