Abstract :
Resonance coupling is a new technology for wireless energy transmission, which can transfer energy in middle distance. This paper analyzed the wireless transmission mechanism based on the coupling model of two spatial isolated hollow coils, and studied the relationship among efficiency, frequency, distance and coil sizes. Further more, the maximum efficiency condition was obtained to optimize the design of resonance coupling system. Experimental results have validated the proposed design method.
