Research on Magnetic Integration Coupling Mechanism of UAV Wireless Power Transfer System

The intelligent inspection method represented by UAV is more and more widely used in the power grid. Wireless charging technology greatly increases the endurance of UAVs which has the advantages of flexibility, safety, and high degree of intelligence. The composite compensation network represented by LCC which has constant voltage or constant current output characteristics is more widely used in wireless charging systems. However, the separate compensation inductor greatly increases the volume and weight of the coupling mechanism. Therefore, the magnetic integration technology is studied to realize the integrated design to reduce the volume and weight of the device. At the same time, the coupling mechanism is optimized to achieve the anti-offset characteristics and lightweight requirements of the UAV. Finally, the system simulation results are given based on the MATLAB simulation platform.
