PURPOSE:To obtain a phase advancing type stabilizer capable of easily lighting a discharge lamp required for high lamp voltage and secondary no-lead voltage without generating flicker or the like on switching by arranging a secondary coil on the side of a leakage transformer in a gap formation position of a central leg iron core. CONSTITUTION:A gap 3 is formed in the central part of a central leg iron core 2 of a leakage transformer iron core, while primary coils 4a and 4b on the side of an in two divided leakage transformer 7 are arranged on both end parts where no gap 3 of the iron core 2 is formed. Further, a secondary coil 5 on the side of the leakage transformer 7 is arranged on the central part where the gap 3 is formed. The divided primary coils 4a-1 and 4b-1 on the side of a booster transformer are in series connected to be impressed with a power supply 8, further the divided secondary coils 4a-2 and 4b-2 on the booster transformer are connected in series while being in series connected to a proper secondary coil 5 on the side of the leakage transformer, and a lamp 10 is connected to an output end of the secondary coil 5 through a capacitor 9. Thus, it is possible easily obtain a stabilizer capable of lighting stably without generating flicker or the like on switching. |
