Abstract :
Based on electromagnetic (EM) field resonantly coupling technology, a novel contactless power transfer system is analyzed in this paper. A detailed field-circuit coupling model is proposed taking into account the influences of near field strength and circuit constraints simultaneously. Therefore, the distribution of magnetic field strength under different angular frequencies and spacing distances are calculated through direct field-circuit coupled method. In the experimental aspect, a resonantly coupling system contains planar disc resonators is designed. It is shown by measurement results that property of system is basically consistent with the results derived in article. Moreover, the solution accuracy is improved through this technology to recharge electrical devices or transfer power.
