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.
