연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

This paper presents a survey of recent wireless power transfer systems. The issue of wireless power transfer is to achieve a highly efficient system with small positioning errors of the facilities setting. Several theories have been presented to obtain precise system design. This paper presents a su...

문제 정의

  • The last topic of this paper was the rectenna efficiency in the microwave range as a means of long range power transmission. The RF to DC conversion efficiency is mainly determined by the performance of the rectifier diode.
  • The last section is devoted to a basic device in the power transfer system, namely a rectenna design to increase the RF to DC conversion efficiency. This paper concludes with a discussion of the issues of wireless power transfer systems.
  • This paper presented three topics in the research fields of wireless power transfer. A simple circuit theory was introduced to explain short range power transfer by the resonator coupling.
  • A basic theory for coil coupling is given by circuit theory [2], [4], and is also explained by a filter theory [5] and others. This paper presents a simple circuit theory based one lectromagnetism to find the coupling efficiency between coils. In practical power transfer applications, the efficiency is a very important factor.

가설 설정

  • Very few papers have evaluated the effect of suppressing harmonics by measuring antenna efficiency. To confirm whether the efficiency is improved by antenna differences, we measured RF-DC conversion efficiency.
