Research on Interoperability of Coupling Structure for UAV-WPT System

摘要

Based on the different tripod structure of unmanned aerial vehicle (UAV), two kinds of common receiver coils and the corresponding transmitter coil structure is analyzed in this paper. The finite element analysis method is used to research the effects of the size, number of turns and spatial position of the transmitter coil on the magnetic field distribution, so as to improve anti-offset capability of coupling mechanism. In order to satisfy the constant voltage power supply for two kinds receiver coils, the planar and DD transmitter coils are placed in the same topology, and the two coils can be used as transmitter and compensating coils for each other. Consequently, the interoperability of the coupling structure is improved.
