Patent ID: 7304436

Claim:
A sustaining pulse generator of a plasma display panel (PDP), comprising: a direct current (DC) converter for converting an alternate current (AC) voltage to a direct current (DC) voltage; a sensor for sensing a level of the AC voltage; a switching part for converting the DC voltage into a square wave; a transformer for inducing the square wave to an output terminal thereof; a controller for controlling a turn-ratio of the transformer in accordance with the sensed AC voltage level; and a rectifier for rectifying the square wave induced to the output terminal and for generating and applying a sustaining pulse to the PDP, wherein the PDP includes a plurality of scan electrodes and sustain electrodes in a first direction, a plurality of address electrodes in a second direction, the first direction being different from the second direction, a plurality of cells, each cell having scan, sustain and address electrodes, wherein the sustaining pulse is provided to the scan and sustain electrodes.
