Abstract
A ballast for an arc discharge lamp load switches high voltage DC at a high frequency based on a low frequency control signal. The switched high voltage is then filtered to remove effects of the high frequency switching. Switching may be accomplished with a high voltage, AC voltage controlled current source generating a high frequency, high voltage substantially rectangular signal at a source output by switching the high voltage DC signal with the low frequency time varying reference signal.
