ABSTRACT:
A variable high-frequency ballast circuit for igniting and operating energy saver discharge lamps includes a high frequency inverter that energizes the lamps with a given high frequency voltage at which reliable lamp ignition is assured. The lamp current is monitored so as to automatically increase the lamp operating frequency to an optimum value as soon as the lamps ignite.
