초록

본 논문에서는 무선전력전송을 위한 정류회로의 RF-to-DC 변환효율 개선에 대해 연구하였다. 정류회로는 지역통과 필터, 다이오드 회로, 직류 통과필터로 구성되어 있는데, 이것들 모두가 변환 효율에 영향을 미친다. 시뮬레이션을 통해 이러한 부분들이 어떻게 변환효율에 영향을 주는지 조사를 하였고, 이러한 내용을 바탕으로 10dBm의 저전력에서 약 50%의 변환효율을 갖는 912MHz의 정류회로를 제작하여 특성을 측정하였다.

This paper examines RF-to-DC conversion efficiency of rectifying circuit for wireless power transmission. The rectifying circuit consists of low pass filter, diode circuits and dc pass filter. All these components may be effect on the conversion efficiency. Using the simulation, we study these components how to effect on the conversion efficiency. On the basis of the simulation results, the 912MHz rectifying circuit with 50% efficiency at low input power such as 0dBm is fabricated and its characteristics are measured.
