  • ENERGY SAVING LUMENS SETTABLE DEVICE FOR FLUORESCENT LAMPS
    Publication number: 20100202166
    Abstract: A circuit to supply an AC voltage to a fluorescent lamp load from an AC supply converts the supply to DC, boosts the voltage in a converter and then drives an inverter from the smoothed boosted voltage in such a manner that the inverter will not start if the load is too low and the inverter frequency is almost constant. The power factor of the circuit is maintaining very close to unity.
