Splitting Effect

Wireless power transfer brings the possibility of connector-free for electric devices. Because there is no electric connection between power source and load, the system employs wireless power transfer based on magnetic resonance becomes safer, more convenient and more reliable. The wireless power transfer system of four-coils based on magnetic resonances is analyzed, including phenomenon of frequency splitting, effect of the angle between the source coil and the device coil, and effect of external objects. Simulation results are presented in this paper.
