Demand and interest in unmanned aerial vehicle (UAV) technologies has been rapidly growing. Most of UAVs use the battery for their operation, despite of its heavy weight and long charging time. The wireless charging system for drones is on increasing demand, to avoid the shortcomings of battery. Typical wireless charging system utilizes the ferrite for improving power transfer efficiency, but the brittleness of ferrite characteristics deters its application to dynamic UAV operation. In this paper we proposed a wireless charging system using the developed soft magnetic composite. For validation, the proposed wireless charging system was implemented with typical wireless charging system. And power transfer efficiency and intensity were measured and compared with conventional ones.
