  • Method and circuit for regulating power in a high intensity discharge lamp
    Patent number: 7187136
    Abstract: A circuit for controlling power to a high intensity discharge lamp is disclosed. The circuit according to one embodiment of the invention comprises a rectifier circuit coupled to receive an alternating current line voltage, and a boost/flyback converter coupled to the rectifier circuit which outputs a regulated DC bus voltage. A power control circuit also couples a feedback signal to the boost/flyback converter to regulate the power output of the boost/flyback converter. A method of controlling power to a high intensity discharge lamp is also disclosed. The method comprises steps of generating a DC voltage for the high intensity discharge lamp by way of a boost/flyback converter; monitoring the DC voltage and the current generated in the boost/flyback converter; and modifying the power output by the boost/flyback converter to regulate power based upon the voltage and the current.
