Wireless Power Transfer System

In this paper, a magnetic resonance coupled wireless power transfer system(MRCWPTS) with series capacitor compensation is studied in order to investigate resonance frequency, and then the system transfer model is presented. Research results show that system resonance frequency is likely to occur splitting and maybe appear two or three resonance frequencies(odd /even mode resonance frequency and nature resonance frequency) in close distance under small load, which increases the system instable, and makes the system difficult to control in resonance frequency. By analyzing of the system, the distance boundary condition when resonance frequency splitting is given, under this boundary the system avoid resonance frequency splitting well, then simulation and experiment results verify the theoretical analysis.
