Abstract:
An improved solid-state fluorescent lamp ballast in which line voltage or directly rectified line voltage is chopped to provide a high frequency input to the lamp permitting smaller reactive ballast components to be used. Also shown are various means of switching, means for isolating the high voltage switches for the logic circuits, driving them and various load circuits.
