Wireless charging microwave power transmission system

Abstract

The invention provides a wireless charging microwave power transmission system, which can effectively perform remote and non-contact wireless charging of a plurality of devices at the same time. The wireless charging microwave power transmission system is achieved by the following technical solution: a charging signal transmitter continuously transmits microwave wireless rechargeable signals to aplurality of charged devices in a rechargeable radiation area through a charging signal transmitting antenna in a pulse mode; a charged device emits a charging request signal, an intelligent multi-beam tracking antenna periodically locates and tracks the charging request signal and searches the charging request signal position of the charged device, according to the determined charging request signal position, a digital processor calculates the amplitude and the phase required at each antenna unit port through a transmitting channel to allow the generated microwave wave beam to align the charged device in the rechargeable area, and the charged device receives the microwave to generate a direct current. By positioning and tracking the charged device, the remote mobile device can be effectively charged.

Description

technical field [0001] The invention relates to a microwave wireless charging system that can be widely used in the fields of smart phones, wearable devices and other consumer electronics products, smart home, automotive electronics, portable medical electronic products, etc., especially for the wireless transmission of energy in the form of microwaves , to realize a microwave wireless charging system for charging one or more fixed or mobile devices. Background technique [0002] With the increasingly rich functions of electronic products, their energy consumption is also increasing, and has gradually become a major obstacle restricting the development of electronic products. When charging, traditional power equipment mainly uses metal wires for power transmission. This "wired" power transmission method has many problems. For example, electric shavers and electric toothbrushes are often used in humid environments, and the existence of electrical connections may cause accide...

AI Technical Summary

Problems solved by technology

Traditional phased array antennas are usually used to transmit or receive microwave signals. The main consideration is the quality of the transmitted signal. The transmission efficiency of the energy carried by the microwave signal itself between the receiving end and the sending end is extremely low.
