Study of High-Power-Factor Single-Stage Electronic Ballast for fluorescent lamps
고역률 단일 전력단을 갖는 형광등용 전자식 안정기에 관한 연구
Abstract
A new low cost single stage high power factor electronic ballast for fluorescent lamps is presented in this paper. The proposed topology is based on integration of two-boost converter and LC type high frequency resonant converter. A ballast is obtained by simple construction, because full bridge rectifier diode is eliminated and simple control circuits is applied. Using two boost converter operating positive and negative half cycle respectively at line frequency (60Hz), operating in discontinuous conduction mode performs high power factor. The simulated and experimental results for 64W fluorescent lamps operating at 45kHz switching frequency and 110V line voltage have been obtained.
