Abstract

In this paper, a technology for a high-efficiency wireless power transmission transmitting and receiving coil that can wirelessly charge a drone is introduced. The drone station implements the ability to charge the battery wirelessly without the need to remove the battery to charge the drone's battery. In order to charge the drone's battery in the shortest time, wireless charging efficiency must be high. In order to increase the wireless charging efficiency of the drone station, a method for manufacturing high-efficiency transmitting and receiving coils and a performance measurement method are presented. Transmitting and receiving coils were manufactured considering the size and weight of the drone so as not to interfere with the flight of the drone. Efficiency of 88% or more was realized at a distance of 40mm or more between the transmitting and receiving coils.

본 연구에서는 드론을 무선으로 충전할 수 있는 고효율 무선 전력 전송 송, 수신 코일 개발에 대한 기술을 소개한다. 드론 스테이션은 드론의 배터리를 충전하기 위해 배터리를 분리 할 필요 없이 무선으로 배터리를 충전할 수 있는 기능을 지원한다. 드론의 배터리를 최단 시간 내에 충전하기 위해서는 무선 충전 효율이 높아야 한다. 드론 스테이션의 무선 충전 효율을 높이기 위해 고효율 송, 수신 코일 제작 방법과 성능 측정 방법을 제시하였다. 송, 수신 코일은 드론의 비행에 방해가 되지 않도록 드론의 크기와 무게를 고려하여 PCB 기판을 이용해 제작하였다. 송, 수신 코일 사이의 거리가 40mm 이상 떨어진 거리에서 88% 이상의 효율을 구현하였다.
