Performance analysis of electronic ballasts in fluorescent lamp with flyback and buckboost converter

Abstract

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 anlaysed 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.
