Optimum Design of Wireless Charging System Based on Magnetic Coupling

Aiming at the problem of insufficient routing inspection endurance of UAV(Unmanned Aerial Vehicle) in power grid, this paper proposed a wireless charging scheme for UAV based on resonance magnetic coupling, analyzed the technical feasibility of high-voltage energy acquisition with double CT structure which is based on the experimental platform of high-voltage energy acquisition module, studied the influence between coil turn and the parameters of CT energy acquisition, designed the power supply circuit of the energy acquisition module which includes peripheral Circuit parameter and battery management Flow. This paper achieved the optimum design of coil parameters for wireless charging unit. The research could improve the endurance of UAV for transmission line inspection and provide support of reliable line inspection which made influence of the power gird safe and stable operation.
