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%.

In this paper, an automated impedance matching circuit is proposed to match the impedance of the transmit and receive resonators for optimum wireless power transfer (WPT). This is achieved using a 2D open-circuited spiral antenna with magnetic resonance coupling in the low-frequency ISM band at 13.56 MHz. The proposed WPT can be adopted for a wide range of commercial applications, from electric vehicles to consumer electronics, such as tablets and smartphones. The results confirm a power transfer efficiency between the transmit and receive resonant circuits of 92%, with this efficiency being sensitive to the degree of coupling between the coupled pair of resonators.
