본 논문에서는 자기공명을 이용한 중전력 무선전력전송시스템을 설계하고 구현한 결과를 소개한다. 무선전력전송시스템은 송신부, 공진부, 수신부로 구성되며 공진기간 전송효율(RF-RF전송효율)은 직경거리에서 70%이상을 가졌다. 구현한 시스템의 전송전력은 최대 100W이며 25W급 옥외 LED전광판, 30W급 노트북, 40W급 모니터, 50W급 서비스 로봇에 무선으로 에너지를 전송하였다. 끝으로, 서비스 로봇의 충전 시스템의 경우 시스템 효율(DC-DC전송효율)은 전송거리가 25cm일 때 약 50%였으며 인체영향을 고려한 전력제어 기술을 적용하여 무선충전 중에 사람의 접근하는 경우 전송전력을 조절하여 전자파로부터 인체를 보호할 수 있도록 하였다.
