ELECTRONIC BALLAST FOR A HIGH VOLTAGE DISCHARGE LAMP, CAPABLE OF MAXIMIZING THE LIFESPAN OF A BALLAST AND REDUCING ENERGY CONSUMPTION BY MINIMIZING A LIGHTING FAILURE RATE

摘要

PURPOSE: An electronic ballast for a high voltage discharge lamp is provided to simplify the structure of a circuit by forming a high voltage generation circuit through the serial connection between an arrester, a capacitor, and a transformer.;CONSTITUTION: A power supply part(210) eliminates the surge of common electricity and the noise of an AC component. A power factor correction part(220) improves the power factor and total harmonic distortion of a driving voltage. A voltage control part(230) controls the voltage value of the driving voltage to a reference voltage value. A power control part(260) controls the voltage value of the voltage control part and a voltage which is discharged to the high voltage discharge lamp. A full bridge part(240) outputs a square-wave voltage for a high voltage discharge lamp. An electronic igniter part(250) applies a square-wave voltage corresponding to the reference voltage value.;COPYRIGHT KIPO 2011
