Wireless power transmission technology is widely used in medical machinery, consumer elec- tronics, electric vehicles and other fields, but the transmission efficiency is still the key factor to limit its development. In order to solve the transmission efficiency of the system, This paper using the method of theoretical derivation, By exploring the coupling coefficient, distance and other efficiency factors, Gets the frequency of the maximum transmission efficiency of the system and adjustable frequency range of meeting the transmission efficiency needs. In addition, we offer to add the incremental coil to improve the efficiency of multi-receiving Wireless power transmission in this paper. The results show that the design in this paper can improve the transmission efficiency and reduce the power loss obviously.
