Wireless power transfer via magnetic resonance coupling is a new technology which energy can be transferred in the non-radiative near-field. In order to improve its power, We presented a new analysis that yielded critical insight into the design of practical system . The basic study on coils design and impedance matching network for hundreds of watts was presented. Based on these analysis, The wireless power transfer experimental device was designed. Experimental results shows that the power can be transmitted is up to 300W in the distance of 2.3 m, the efficiency is 60%.
