碩士 === 大葉大學 === 電機工程學系碩士班 === 93 === A single-state high power factor electronic ballast for cold cathode fluorescent lamp is designed in this paper. The major algorithm of circuit includes the EMI filter circuit and the single-stage electronic ballast. The EMI filter circuit will filter the high frequency harmonic disturbance. Moreover, the input current will follow, the input voltage by using the single-stage electronic ballast to obtain a high power factor and the stable power for the cold cathode fluorescent lamp. A high power factor electronic ballast was designed in this paper. The simulation and that results were conducted also.
