Abstract (en)
Electronic Ballast system for high intensity gas discharge lamps (HID lamps) formed by a power factor correction circuit, a Buck - type regulator source, a DC-AC converter with an operating frequency equal to 150 Hz, an electronic igniter circuit, a power control circuit and a microprocessor integrated circuit which comprises means for sensing voltage and current, means for controlling output power to the ballast, means for controlling triggering of the igniter and means for communicating in series with peripheral circuits. The power control circuit and the microprocessor allow the use of the same ballast system with different lamp wattages. <IMAGE>
