Title: Circuit for driving a gas discharge lamp load.
Inventor: MOISIN MIHAIL S
IPC: H05B41/282
Filed: 2000-05-24
Abstract: A circuit for driving one or more gas discharge lamps (102, 104, 106) from a nominal-level voltage supply includes: a voltage boost IC (144); a self-oscillating, series-resonant oscillator (196, 198, 178, 180) for producing a high-frequency output voltage for application to the lamps via an output-coupling transformer (212); and a voltage clamp (215A, 215B) coupling the transformer to the oscillator input (174, 176). The voltage boost IC is arranged to regulate the power drawn by the circuit to a constant level if the supply voltage is greater than 95% of its nominal value. If the supply voltage falls to less than 95% of its nominal value, regulation is lost and the circuit draws less power in proportion to the fall in the supply voltage. If the supply voltage falls to less than 90% of its nominal value the clamp operates to reduce the power drawn by the circuit at a rate greater than that of the fall in the supply voltage. The circuit thus enables an electric utility generating the voltage supply to reduce the power drawn by the circuit by reducing the supply voltage to less than 95% of its nominal value.
