| Wireless power transfer has obtained fruitful research results in recent years.Compared to the power transmission of traditional physical medium as medium,this power transmission mode has high security and strong advantages,effectively solving the problem of access.The friction of Iife,especially in the harsh electricity environment,represents a revolutionary progress in energy transmission.Harmonic coupled radio energy transmission(MCR-WPT)is a new technology in the field of WPT.Because of its advantages in transmission efficiency and transmission distance,the technology has been highly concerned by many researchers at home and abroad since its birth.In the first part of this paper,the basic principle of magnetic coupled resonant radio transmission is expounded.Through the modeling of theory,two port theory and theoretical basis,the mechanism of radio energy transmission is deeply analyzed and studied,so as to prove the consistency of the analytical method.The second part,based on the theory of circuit mutual inductance,derives the voltage,and so on from the series compensation structure model,and analyzes the influence of the coil inductance.coupling coefficient and frequency on the transmission performance of the resonant system.In the last part,the magnetic coupling radio energy is built on the basis of the simulation,and the parameters of the system performance are simulated and the related experimental data and the waveform are obtained.The results of the experiment are in agreement with the conclusion of the analysis in this paper.The paper has 41 figures,10 tables and 64 references. |
