Abstract

This paper presents a new method for designing a ballast that can provide dimming control of an electrodeless fluorescent lamp. Frequency control of lamp power is inappropriate because the lamp coefficients such as equivalent impedance, coupling coefficient of the transformer, and plasma resistance are a function of lamp power. In this paper, the dimming is achieved by controlling the DC_Link voltage in relation to the lamp power. The DC_Link voltage is controlled by a buck converter. Simulation and experimental results of the proposed design method are presented in order to validate the proposed method.

본 논문은 무전극램프의 조광제어에 관한 안정기 설계방법을 제안하였다. 주파수 가변을 통한 전력제어는 램프의 등가 임피던스를 나타내는 유도코일간의 결합계수, 플라즈마 저항은 전력에 대한 함수이기 때문에 부적합하다. 따라서 본 논문은 직류링크전압을 가변함으로서 램프 임피던스와 독립적으로 램프의 출력 전력을 제어함으로서 무전극램프를 조광제어 하였다. 직류 링크 전압 가변방법은 벅 컨버터에 의해 제어하였으며, 제안된 설계 방법의 시뮬레이션과 실험 결과를 통하여 논문의 타당함을 증명하였다.
