The classical series-resonant parallel-loaded half-bridge inverter is the power stage analyzed in this paper. In addition, the preheating process is based on the imposition of a constant rms current through the electrodes, in order to provide a proper value of the R-h/R-c ratio before the lamp start. According to the proposed methodology, it is possible to set suitable operating points for, the electronic ballast, considering optimal conditions for the lamps electrodes. Therefore, the proposed methodology for setting the preheating and steady-state operation is a complete platform to the design of electronic ballasts for hot-cathode fluorescent lamps.899-911engelectrodes filamentselectronic ballastsfluorescent lamp modelpreheating processR-h/R-c ratioArtigo10.1109/TPEL.2007.896990WOS:000246380400023Acesso restrito6427185658143370
