Abstract

In this paper, a photovoltaic switch is suggested that is operated by solar module, a substitute for CdS(Cadmium Sulfide) of most existing automatic switches and thus is powered by its renewably charged battery, and its usability is investigated through various experiments. At first the characteristics of CdS and the operation principle of the existing automatic switch are investigated, and then the characteristics of solar module are examined. These preparatory research shows the possibility of substitution of solar module instead of CdS in light activated switch. Secondly the suggested photovoltaic switch's circuit is designed, implemented and then its experimental comparison data shows the possibility for the replacement of the existing switch to the suggested switch, and furthermore its superiorities.

본 논문에서는 CdS(황화 카드뮴) 광센서란 소자를 태양광 모듈로 대체하여, 신재생에너지를 통한 충전도 하며 이 전력으로 동작하는 태양광 스위치를 제안하고 이의 효용성을 실험/검증하고자 한다. 우선 기존의 CdS 광센서와 이를 포함한 자동 점멸 스위치의 동작 원리를 조사해 본 후, 태양광 모듈의 특성을 조사함으로써 기존의 광센서를 태양광 모듈로 대체가능할 지를 분석해 본다. 그 가능성을 확인해 본 후, 태양광 스위치 회로를 설계 및 구현한 후, 이의 특성을 실험해 봄으로써 기존 스위치를 대체 가능함을 보이고 그 특성들을 비교/평가해 본다. 연구 결과 제안하는 태양광 스위치가 기존의 자동 점멸 스위치를 대체 가능함을 확인하였을 뿐만 아니라, 보다 많은 장점들을 가지고 있음을 확인하였다.
