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;

Description

technical field [0001] The invention belongs to the technical field of semiconductor integrated circuits, and in particular relates to a wireless charging system. Background technique [0002] Wireless charging technology is a new technology. Compared with the traditional wired charging method, wireless charging is more convenient and safe, especially because it is not limited by wires, chargers, sockets and other factors, wireless charging technology is very convenient to use. [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, 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...
