A design method for electronic ballast for fluorescent lamps

This paper presents a new design methodology, analysis, and practical considerations about series parallel resonant filter, LCC, for electronic ballasts employing the self-oscillating driver circuit. Designs equations and graphic methods are presented, obtained by analysis of Fourier series, Tsypkin's Locus and stability tests. The lamp high frequency supply is given by the half-bridge converter, and the verification of this approach is guaranteed by simulation and experimental results.
