Patent CA-2605610-A1 (CA)
Inventor: QUAZI FAZLE S
IPC: H05B41/24
Filed: 2006-04-12
Abstract: The control circuit for maintaining constant power in power factor corrected electronic ballasts and power supplies maintains constant power in a variable load. This constant power control circuit provides a closed loop constant power management process for gas discharge lamps by adding a scaled lamp voltage to a scaled voltage that is equivalent to the measured lamp current.  This sum is then fed to a comparator for comparison with a fixed reference voltage. If there is a difference between the sum and the reference voltage, the comparator sends this information to an error amplifier of the gas discharger lamp power control circuit for corrective measures and closed loop control of gas discharge lamp power. Since the sum always must attain the same value as determined by reference voltage, when the lamp voltage increases from its nominal or initial value, the lamp current is decreased by a corresponding ratio to maintain a constant power in the gas discharge lamp.
