Abstract: Aim

ing at the endurance of UAV, this paper adopted a method of installing a charging platform on a transmission tower and MCR-WPT to install the transmitting coil and the receiving coil on the charging platform and the UAV respectively. For UAV charging,the output power and transmission efficiency of the MCR-WPT system were required to be improved. In this paper, differential evolution algorithm was used to optimize the transmission distance, resonant frequency and load resistance of the two-coil MCR-WPT system. It could be seen that the output power of the dual coil MCR-WPT system had been improved and the transmission efficiency had increased from the original 0.40 to 0.68,which verified the effectiveness of the optimization method.

Key words: MCR-WPT, output power, transmission efficiency, differential evolution algorithm, charging platform, optimized design
