Abstract: An electronic transformer system for powering gaseous discharge lamps includes an output transformer having a load connected to a secondary winding and having a power storage capacitor connected in series with a primary winding, a charging transistor connecting one end of the series combination to one polarity terminal of a voltage doubler DC power source, the other end of the series combination connected to the other polarity terminal of the power source, a discharging transistor connected across the series connected primary and capacitor, and an oscillator connected through a coupling transformer to the bases of the transistors. The oscillators alternately causes the transistors to switch into conduction to thereby alternately cause the charging and discharging of the capacitor through the output transformer. The charging and discharging characteristics of the capacitor result in the turn off of the transistors occurring at low current levels whereby turn off of the transistors is accelerated.
