Experimental System Design of Wireless Power Transfer Based on Witricity Technology

Wireless power transfer based on witricity technology is a new technology which energy can be transferred via coupled magnetic resonances in the non-radiative near-field. In order to verify its feasibility, coupled mode theory and power transfer system structure was proposed in this paper. Based on these analysis, The wireless power transfer experimental device is designed. Experimental results shows that the power can be transmitted is up to 30W, the transfer efficiency is more than 60%, the maximum distance of energy transfer can reach to 450mm.
