Abstract

In this Paper the electronic ballast using the SEPIC(Single Ended Primary Inductor Converter) converter for the multiple electrodeless fluorescent lamps is proposed, which has the structure of the active PFC and self oscillating function. The SEPIC converter system has the characteristics of the power factor with low input current harmonic distortion. The proposed control method is based on the aveage-current-mode using the dedicated integrated circuit UC3854. The proposed electronic ballast has the reduction effect for the energy and manufacturing cost because it is designed for tripple electrodeless fluorescent lamps. The experimental results shows that the power factor is higher and the THD is lower.

본 논문에서는 능동역률보상(PFC)의 구조를 가진 SEPIC 컨버터를 이용한 무전극 형광램프(electrodeless fluorescent lamps)용 전자식 안정기를 제안하였다. SEPIC 컨버터는 입력 전류의 낮은 고조파와 고역률의 특성을 가진다. 제안된 제어방법으로는 UC3854의 적분회로를 이용한 것으로 이 기술은 전류연속모드로 동작하는 역률보상 및 과전류보호를 제공하는 매우 간단한 제어 회로이다. 제안된 무전극 형광램프용 전자식 안정기는 3개의 무전극 형광램프용으로 설계되어 기존의 무전극 형광램프용 전자식 안정기보다 에너지 및 제작비 절약 효과가 크다. 제안된 안정기의 특성을 측정하기 위해 실험을 실시하였으며 이를 통해 고역률과 낮은 THD를 확인하였다.
