PERFORMANCE ANALYSIS OF ELECTRONIC BALLASTS IN FLUORESCENT LAMP WITH FLYBACK AND BUCK-BOOST CONVERTER

This paper presents fly back and buck-boost converter for power factor improvement in electronic ballast of fluorescent lamp. The performance of the model is analyzed during intermittent mode in high frequency DC-AC inverter. The examination, plan, demonstrating and imitation of high power factor electronic ballast for a lamp are accomplished by continuous dc voltage. The resonant filter is carried to regulate the square waveform provided by the inverter weakening the higher order harmonics, thus reducing the total harmonic distortion. The power quality keys are estimated of ac mains current of total harmonic distortion and crest factor to validate its suitable performance. The Fly back and Buck-Boost based electronic ballasts were simulated using MATLAB Simulink and results were compared.
