ABSTRACT:
A ballast, or power supply circuit, for gas discharge lamps of the type using IC control based gate-drive circuitry for controlling a pair of serially connected switches of a d.c.-a.c. inverter. More particularly, the invention relates to a ballast having a resonant feedback circuit drawing continuous input current from a wide range of source voltages to satisfy requirements of phase control dimmers. Even more particularly, the invention relates to a universal platform for phase dimming discharge lighting using the Ballast and a discharge Lamp with a phase dimming circuit.
