A circuit for the efficient generation of high voltage pulses for the initiation of conduction in gaseous discharge lamps, the effective suppression of potentially harmful voltage surges resulting from derangement of one or more electrical, current-carrying mechanical, or mechanical components within the overall gaseous discharge lighting apparatus, and reduction of radio frequency interference resulting from the normal and deranged operation of the overall gaseous discharge lighting apparatus. The ignitor/suppressor includes a semiconductor switching device, a capacitor of special characteristics, a transformer of special construction, and a resistor for the generation of high voltage pulses. The ignitor/suppressor also includes a semiconductor switching device, a capacitor of special characteristics, and a resistor for the effective suppression of abnormally high voltages. The circuit configuration of the ignitor/suppressor eliminates any corona-discharge induced insulation damage within the ballasting apparatus normally employed with gaseous discharge lamps. Features of its construction eliminate any corona-induced insulation damage within the ignitor/suppressor itself.
