Abstract

The invention belongs to the field of electronic communication and relates to a wireless energy transmission method, in particular to a wireless energy transmission method with an adaptive variable receiving coil. The method proposed by the invention controls the output voltage and improves the transmission efficiency by changing the area size of the RX coil in real time under the condition that the TX coil is fixed. While stably outputting sufficient power, it can avoid damage to the circuit board and improve electromagnetic compatibility. Not only that, this method can reduce voltage regulator chips in RX, thereby further improving the overall transmission efficiency. While stably outputting sufficient power, it can avoid damage to the circuit board and improve electromagnetic compatibility.

Description

technical field

[0001] The invention belongs to the field of electronic communication and relates to a wireless energy transmission method, in particular to a wireless energy transmission method with an adaptive variable receiving coil. Background technique

[0002] The wireless energy transmission system based on the electromagnetic field (hereinafter referred to as the system) generally consists of two parts: an energy transmitting device (hereinafter referred to as TX) and an energy receiving device (hereinafter referred to as RX). Its working principle is to realize the process of energy transmission from TX to RX through the conversion of alternating electromagnetic field. According to the principle of physics, when TX and RX generate magnetic resonance (or resonance) with each other, the size and efficiency of the transmitted energy will be greatly improved.

[0003] Usually, in order to obtain a sufficiently large transmission efficiency and a specific output voltage...
