Abstract :
This paper presents the analysis, design and practical considerations of several low cost high-power-factor ballast for compact fluorescent lamps. The proposed topologies are a combination of a boost converter and a half-bridge parallel resonant converter. The high frequency supply to the lamp is made by a self oscillating half-bridge converter, using integrated circuits IR2151 and IR51HD420. The high-power-factor is guaranteed by using a boost converter operating in discontinuous conduction mode. These topologies have been developed for 20 W compact fluorescent lamps for 110 V, 60 Hz utility line
