Wireless charging system

Abstract

The invention discloses a wireless charging system, comprising: a power module (101), a first rectifying module (102), a filtering module (103), a microwave excitation module (104), a power module (105), and a transmitting antenna (106), a receiving antenna (107), a second rectifying module (108), and an energy storage module (109). The receiving antenna (107), the second rectifying module (108),and the energy storage module (109) are electrically connected in sequence. The wireless charging system of the invention provides a microwave wireless charging mode, the conversion efficiency of thewireless charging system can be effectively improved by a double amplification rectifier circuit and a high mobility Schottky diode, and the problem of low conversion efficiency of the conventional wireless charging circuit is solved.

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...

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;
