Abstract
제안된 회로는 교류 입력 전원부와 무손실 스너버 회로가 부가된 DC-DC 컨버터와 DC-AC 변환을 위한 인버터로 구성하였다. 변환된 등가회로를 이용하여 형광램프의 특성을 만족시킬 수 있는 최적의 회로상수를 결정해서 설계함으로써 기존의 인버터 직류측에서 발생되는 맥동주파수에 의한 왜형파 발생을 제거하고 인버터의 입력전류를 불연속이 되도록 하므로써 맥동율과 스위칭 손실을 현저히 감소시켰다. 이러한 모든 결과를 증명하기 위하여 40 W 직관형 형광램프를 대상으로 실험하여 고조파의 발생을 측정한 결과 제안된 전자식 안정기의 우수성을 확인하였다. Proposed electronic ballast circuit for harmonic reduction includes adding lossless snubber circuit to DC-DC converter. To get inverter for changing DC-AC, a lamp has been changed to equivalence resistance in the standard lamp voltage and current data, also inverter circuit has been interpreted by being changed to R, L, C equivalence circuit. Using converted equivalent circuit, the most suitable circuit constant which can satisfy the characteristics of fluorescent lamps has been decided on and finally designed. It could not only eliminate distortion waveform from pulsation frequency in inverter direct side current but also reduce considerably pulsation rate and switching loss by making input current of inverter discontinuous. The validity for the results of this study has been verified through the experiment to measure harmonic occurrence after applying a newly-manufactured product of electronic ballast to 40 W line tube style fluorescent lamps.
