Novel Method

In order to solve the problem that electromagnetic induction widely used now is just suited to short distance transmission, and study on the transmission characteristics of wireless power transmission system based on magnetic resonant coupling, a novel method that the two separate-coupling coils achieve wireless power and information synchronous transmission is proposed. The basic theory of wireless power transmission and information system is introduced. The condition that resonant frequency splitting phenomenon is produced of a contact-less power transmission system has been deduced, and it depend on the length of distance between the two coils. The principle prototype of transmission system is designed, and transmission characteristics of the system are analyzed by simulation and experiment. Based on circuit formulation, maximum efficiency is found to exist. The results show that the method of wireless power and information synchronous transmission system is in agreement with theoretical analysis.

Power Transmission System

In order to research the relationship between coupling distance and transmission efficiency, study on the transmission characteristics of magnetic resonant coupling for wireless power transmission system, simulation model of wireless power transmission system via magnetic resonance coupling were established based on the theory of two ports network analysis method. The frequency expression of maximum efficiency and the resonant frequency splitting phenomenon condition of a contact-less power transmission system were derived. In a weak coupling at resonance, magnetic resonant coupling can transfer energy with high efficiency. The resonant frequency changes from two to one depending on the critical condition. Until a certain distance, maximum efficiencies are not got. The transmission characteristics of this system were researched by simulation software and experiments. The results show that the transmission characteristics are consistent with theoretical analysis and simulation.
