Abstract

슬립램프의 응용은 소형으로 디자인되는 원리를 이행하므로 작은 사이즈의 전자식 안정기가 요구된다 하지만 기존의 <TEX>$50{\sim}60Hz$</TEX>에서 동작되는 자기석 안정기들은 현저한 플리커(깜빡거림) 현상, 높은 손실, 큰 파고율 그리고 무거운 단점을 가지고 있다. 본 연구에서는 이러한 문제들을 해결하기 위해서 35W급(T5급) 형광등을 동작시키기 위한 제안된 새로운 타입으로 구성된 전자식 안정기로 정류기, 역률개선, 직렬 공진 하프 브리지 인버터 그리고 압전 변압기를 구성한 시스템을 제안하였다. 이 같은 압전 변압기를 이용한 전자식 안정기 구성으로 35급(T5급) 형광등을 성공적으로 동작시킬 수 있었다. 제안된 전자식 안정기를 약 <TEX>$75{\sim}79kHz$</TEX>의 주파수로 구동 시켜서 실험한 결과 25분 구동 후에 형광램프는 시스템 전체 안정기의 역률과 효율은 각각 0.95, 0.86%의 양호한 결과를 얻을 수 있었다. It is required small size electronic ballast to fullfill the design philosophy of miniaturizing in the application of slim lamps. However, the traditional magnetic ballasts operated at 50-60Hz have been suffered from noticeable flicker, high loss, large crest factor and heavy weight. In this study, in order to solve these problems, It was proposed for driving 35W Class fluorescent lamp in the new type of electronic ballast, which is composed of rectifier, active power factor corrector, series resonant half bridge inverter and piezoelectric transformer. A 35W class(T5 class) fluorescent lamp is driven to successful by the fabricated ballast with piezoelectric transformer. Experimental results, It is proposed to driving the lamp using a electronic ballast at operating frequency of <TEX>$75{\sim}79kHz$</TEX> approximatively. It is operated after for 25 min that were obtained good results of the input power factor of 0.95 and efficiency of 86%, respectively.
