초록

최근 컴퓨터, 전기, 전자, 통신, 반도체 장비 등의 전기적 외란에 민감한 부하 설비의 사용이 증가함에 따라 전력 품질에 대한 관심이 높아지고 있다. 더 나아가서는 정밀 부하 장비들에 가장 빈번하게 발생하는 순간 전압 강하는 전력 품질 향상을 위해 적정한 보상이 필요하게 된다. 이를 위해 전기 이중층 커패시터 (EDLC : electric double layer capacitor)를 사용한 순간전압강하 보상장치가 개발되어 적용되고 있다. 본 논문에서는 순간전압강하 보상장치 (DVR : dynamic voltage restorer)에 사용되는 전기 이중층 커패시터(EDLC)에 비해 동일 사이즈 대비 에너지 밀도가 높은 하이브리드 커패시터 (hybrid capacitor)를 적용하는 연구를 하였고, 또한, 유도등의 비상 전원으로써 10년 이상의 수명을 보증할 수 있는 제품으로 하이브리드 커패시터 (hybrid capacitor)의 적용 가능성을 확인하였다.

Recently, Interest in power the quality was increased because of increasing the use of sensitive load equipment into an electrical disturbance such as computer, Electricity, Electronics, Telecommunications and semiconductor device. In addition, To enhance power quality, the instantaneous voltage drop occurred in precision load equipment is a need for proper compensation. In order to solve the problem, The developed dynamic voltage restorer (DVR) using an electric double layer capacitor (EDLC) has been applied. In this paper, We will do study to apply hybrid capacitors that have high energy density to the same size compared to the EDLC to DVR. Also, As a emergency luminaires of emergency power supply that we can support more than 10 years of life was confirmed the applicability of hybrid capacitor.
