Abstract
전력선 통신에서 사용되는 비접촉식 커플러의 신호 전달 특성을 향상시키기 위한 비접촉식 커플러의 구조와 자 기장 결합에 대한 연구를 수행하였다. 비접촉식 커플러의 결합 구조를 분석하였고, Rogowski 코일을 이용한 커플러와 자성체 코어를 이용한 커플러를 제작하여 구조에 따른 신호 전달 특성을 분석하였다. 집중 정수 소자와 임피던스 트 랜스포머를 이용한 임피던스 매칭법을 제안하여 협대역과 광대역에서 신호 전달 특성을 향상시켰고 전달 신호의 크 기는 대역폭과 트레이드오프가 있음을 보였다. 본 연구는 추후 부하 변동에 따른 임피던스 매칭 연구에 도움을 줄 수 있다. We investigated the structure of inductive coupler and its magnetic coupling to increase the transmission coefficient for power line communication. A Rogowski coil, which is an air-cored inductive coupler, and a magnetic cored coupler were fabricated to analyze the transmission coefficient for different coupler parameters. This paper proposes the impedance matching method using lumped elements and an impedance transformer to increase the transmission coefficient. In the experiment, the transmission coefficient of the proposed system was increased in both narrowband and broadband cases, and a trade-off between the transmission coefficient and the bandwidth was shown. This method will be useful for the further study of impedance matching with the load variation.
