Abstract

To ensure the efficient operation of high-power (30 kw) wireless power transmission, this paper proposes a parallel doublelayer rectangular coil with rounded corners that improves the transmission effi ciency through parameter optimization. Finally, an experimental platform is established to verify the accuracy of the parameter optimization. The transmission efficiency of the optimized coil is increased from 82.5 to 91.3% when the transmission distance is 150 mm, and the transmission efficiency is increased by 15.8% and 30% when the unidirectional and bidirectional offset distances are 100 mm, respectively. In addition, two shielding methods, expanding shielding and vertical shielding, are proposed. Experimental results show that these two shielding methods can effectively reduce the edge effect of the traditional shielding structure and improve the transmission characteristics and electromagnetic safety.
