Inductive Power Transfer (IPT) systems have successfully been developed and used to replace traditional conductive power transfer systems where physical connection is either inconvenient or impossible, such as biomedical implants, undersea vehicles, and contactless battery chargers of robots, for providing power to movable or detachable loads. Inductive Coupling uses magnetic fields to transfer power. There is a primary coil, which generates a magnetic field. Then there is another secondary coil which is composed of a capacitor and a coil, the capacitor creates a circuit with the primary and secondary coils. This paper discusses design method and several implementation alternatives for wireless energy transmission systems. It presents realization examples for these alternatives. Wireless energy transmission is investigated in numerous convergence applications due to its simplicity and advantages.

이 논문은 무선 전력 전송을 이용하는 마우스의 급전 패드와 리시버 설계 방법을 제안한다. 마우스의 급전 패드는 코일의 턴간 간격을 불균등하게 조절하여 균일한 자기장을 급전 패드 상에서 얻게 하며, 집전코일은 급전코일과 비교해 크기가 작기 때문에 낮은 결합계수와 품질계수를 가져 원하는 전압을 얻기 어려운데 이를 위해 PCB 코일을 멀티레이어로 제작하고 PCB 패턴의 폭을 조절하여 높은 인덕턴스를 갖게 설계한 후 유한요소해석을 통해 설계한 시스템을 시험했다.
