Wireless power transfer (WPT) is a biocompatible and flexible, convenient and stable energy transmission technology, has a huge application market in consumer electronics and implantable medical aspects. With regard to WPT, improving the transmission efficiency has always been a great challenge. In this paper, a novel four coil wireless energy transmission system based on magnetic resonances analyzed, the formula of quality factor, transmission distance and transmission efficiency is derived. A new coil structure parameter design is proposed. Through the model simulation of the number of turns, the number of strands and the pitch of the turns, the quality factor and inductance of the coil are analyzed by the electromagnetic simulation software HFSS, and the optimal structural parameter values are obtained. The coil with the optimal structural parameters can reach 102 at 13.56 MHz frequency. These structural parameters provide effective reference and guidance for obtaining high quality factor coils and efficient wireless energy systems.
