Abstract

Industrial machines have constraints on movement due to its wire for power supply. Recently, the research on wireless power supply for industrial machine which is required to move freely is receiving a lot of attention. In this paper, we suggest a magnetic induction system which can charge a equipment's battery with wireless at a close range. The system was designed to operate at 13.56 MHz and a distance of 20~30 mm between the transmitting and the receiving power module. From experiment, it was found that it takes about 135 minutes for charging the battery with about 15 V using the proposed system.

산업용 기기는 전력 공급용 전선으로 인해 이동성에 제약이 따른다. 최근 자유로운 이동성이 요구되는 산업용 기기의 무선 전력 공급에 관한 연구가 많은 주목을 받고 있다. 본 논문에서는 근거리에서 장비의 배터리에 무선으로 전력을 공급하는 자기 유도방식의 시스템을 제안한다. 제안하는 시스템은 13.56 MHz에서 동작하며, 송수신 전력 모듈간의 거리는 20~30 mm으로 설계하였다. 실험을 통해 제안하는 시스템으로 약 15 V 의 배터리를 충전하는데 135 분이 걸리는 것을 확인하였다.
