ICT 기반의 무선전력전송 시스템 개발

Abstract

Abstract Recently, wireless power transmission has attracted much interest and is the subject of much research in industry and academia. As its name implies, it is a technology which involves transferring power without wires. This paper presents the design of an ICT-based wireless power transmission system. The proposed system consists of a wireless transceiver unit and high-efficiency coil unit, which can increase both the transmission efficiency and the effective power distance. In particular, the wireless transceiver unit was designed to work with the ICT technique toenable real-time remote monitoring. Also, studies were done relating to the effect of reducing the standby power. Theoptimal frequency of IGBT devices used in industrial wireless power systems of 20[KHz] was utilized. The values of 23.9[  ] and 2.64[  ] were selected for L and C, respectively, through many field experiments designed to optimize the system design. In addition, an output current controlling algorithm was developed for the purpose of reducing the standby power. The results presented in this paper represent a 75[%] to 85[%] higher power transmissionefficiency with a 10[%] increase in the effective power transmission distance compared with the existing systems. Asa result, the proposed system exhibits a lower standby power and maintenance costs. Also, the designed wireless transceiver unit facilitates fault detection by means of user acquired data with the development of the ICT appliedprogram.
