Characteristics of frequency splitting in coupling resonance power transmission system

The wireless power transmission system based on magnetic coupling is a research topic in scientific and industry for it can achieve middle range power transmission with high efficiency. The authors have done research on its possible fre- quency splitting in the transmission process. By FEKO the magnetic coupling resonant wireless power transmission system is modeled and analyzed to verify the phenomenon. We point out the limitations of previous solving frequency splitting meth- od. And this paper presents a feasible method to eliminate the influence of frequency splitting phenomena on the transmis- sion system, for the follow-up it can provide reference for the design of magnetic coupling resonance wireless power trans- mission system.
