Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a mobile terminal wireless power supply system. Background technique [0002] In the field of communications, with the development of industrial production and science and technology (especially power electronics technology), electrical equipment is becoming more and more popular, and higher requirements are placed on the power supply methods of existing electronic equipment. Since the traditional power supply method basically adopts the transmission method of direct conduction of contact electric energy, and this method has problems such as poor mobility, unsafety, and especially not suitable for harsh environments (underwater, humidity, etc.), it can no longer meet social development. demand. Therefore, based on this problem, a technology that transmits electric energy in a non-electrical direct contact manner, that is, wireless power transfer technology (WPT), ...

Problems solved by technology

This non-contact charging method can no longer meet people's needs, and in recent years, wireless power supply methods based on electromagnetic waves have become a research hotspot.

[0004] However, in the current published literature, there is no prior art that provides a complete solution from the emission of energy electromagnetic waves to the reception and use. The prior art closest to the present invention is the invention patent "Wireless Power Supply for Mobile Terminals" with application number 201310544227.8 Device", the patent discloses a wireless power supply device, the structure of which includes a receiving antenna, a rectifier circuit, a protection circuit, an energy storage device and a power management circuit, which can convert electromagnetic waves received by the receiving antenna into direct current for charging mobile terminals , but the patent does not solve the problem of the source of the energy electromagnetic wave that can be received by the device and how to carry out matching transmission between the transmitting end and the receiving end.
