Low-power load wireless electric power transmission system based on chaos

Abstract

A low-power load wireless electric power transmission system based on chaos comprises a chaotic signal generating circuit, a chaotic electric power signal generated by the chaotic signal generating circuit enters a switch driving circuit, the switch driving circuit makes voltage of the chaotic electric power signal reach a voltage level required by an energy transmitting system, and finally the chaotic electric power signal is sent out through the energy transmitting system; after an energy receiving system receives the chaotic electric power signal, the chaotic electric power signal is transmitted into a high-frequency rectifying circuit, and the high-frequency rectifying circuit converts the alternating current energy of the chaotic electric power signal into direct current energy to be used by a load; fractal antennae are adopted in both the energy transmitting system and the energy receiving system. The low-power load wireless electric power transmission system based on chaos has the advantages that first, the chaotic signal generating circuit is used as a signal generator; second, the switch driving circuit is high in working frequency and simple in structure and thus can well drive a switching tube; third, due to the fact that the fractal antennae are adopted in both the energy transmitting system and the energy receiving system, the size of the antennae can be effectively shrunken, electric power transmission efficiency is improved, and electric power transmission distance is increased.

[0002] Since the discovery of the law of electromagnetic induction in 1840, people have begun to study wireless technology. The communication technology based on mobile phones and networks has completed a leap from wired to wireless, but the wireless transmission of energy has developed very slowly. So that almost all current charging or actual power transmission must use tangible media, such as: use metal wires (wires and cables) as the main connection, even for short-distance power transmission (such as computers, TVs, etc.), This increases the cumbersome process of actual wiring to a certain extent

However, the transmission distance of the existing wireless energy transfer technology is either too short or cannot pass through obstacles, which cannot meet the current needs. In the past two years, the magnetic coupling resonance wireless energy transfer technology has developed rapidly as an emerging wireless energy transfer technology. , and caused great repercussions in the field of wireless energy transmission
