초록

본 연구에서는 실내조명을 위한 LED 조명용 정전류 컨버터를 설계하고 제작된 SMPS의 전기적 특성을 측정하였다. 출력전류가 300mA 일 때 최대 85%의 효율을 나타내었으며 100~400mA의 범위에서는 70% 이상의 효율을 나타내었다. 또한 0~250mV의 제어신호를 이용하여 디밍레벨 0~100%의 범위를 모두 제어할 수 있었다.

In this study, the constant current converter for LED lighting was designed and the electrical characteristics of the fabricated SMPS was measured. When the output current is 300mA the maximum efficiency of 85% was shown and the output current is in the range of 100~400mA efficiency over 70% were exhibited. Also the dimming levels control over the range of 0 to 100% was possible by using a control signal of 0~250mV.
