본 논문에서는 자기공명 방식을 이용한 25W급 무선전력 전송 시스템을 설계 및 구현하는 것을 제안하고 있다. 본 논문에서 제안하는 자기공명 방식 무선전력 전송 시스템은 100W급 Class-F 송신기, 1.7MHz대역의 송수신 공진기, 40W급 Full-bridge 다이오드 수신기로 구성되어 있다. 특히 제안된 시스템은 수신기에 전달되는 전력이 부하를 구동할 수 있는 적정레벨로 유지될 수 있도록 송신기와 수신기 사이의 통신을 이용한 송신전력제어 기능을 구현하여 송신기가 최적의 전력을 송신하여 불필요한 전력 낭비를 줄일 수 있도록 구현되었다. 본 논문에서 제안된 시스템 및 송신전력 제어기능을 기반으로 다양한 기기에 동일한 기능의 적용이 가능하며 상용화에 보다 근접할 수 있을 것이다.
