Abstract

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.

자기유도형 전력전송시스템은 의생명 임플란트, 해저 수송, 그리고 로봇의 무접촉 배터리충전 등에 대한 이동형 및 분리형 부하에 전력을 공급하는 물리적 접촉이 요구되는 기존의 방식을 대체하여 성공적으로 개발이 진행된 시스템으로 알려져 있다. 자기유도결합은 자기유도방식을 이용하여 전력을 전송하는 방식으로 1차측 코일(송전코일)에서 발생되는 자기장을 2차측코일에 전송하는 원리이다. 송전측 코일에서 발생된 자기장을 커패시터와 코일로 이루어진 2차측 코일(수전코일)로 구성된 리시버회로에 전송하는 구조로 송전부와 수전부 코일을 갖는 회로로 구성된다. 본 논문에서는 자기유도결합을 적용한 무선전력전송시스템에 대한 수전측 토폴로지 설계 및 적용방법에 대해 연구하였다. 적용된 무선 전력전송방식은 적용의 편리성과 폭넓은 어플리케이션으로 인해 다양한 융합형 응용장치의 적용이 가능하다.
