<p>Energy recovery sustain circuit for an AC plasma display panel, is disclosed, having first, and second energy recovery sustain driving parts for supplying sustain pulses of Vo volt to a load capacitor in the AC plasma display panel, each including an output terminal, an inductor, a first capacitor, a second capacitor, first capacitor discharging means, second capacitor discharging means, first capacitor charging means, second capacitor charging means, first to fourth voltage sustaining means, thereby, since a plurality of capacitors are provided for temporary storage of a discharge energy of the load capacitor, which is charged back to the load capacitor many times, the present invention has an advantage in that a power consumption of the panel can be reduced than the background art panel in a sustained driving, the system giving and taking charge and discharge energies to/from the load capacitor provided in the present invention allows linear compensation of the capacitance of the load capacitor, and as the present invention provides a rising time of the sustain pulse of a maximum resonant point to the panel regardless of the variation of the capacitance of the load capacitor, an energy loss can be reduced and a stable sustained driving of the panel is possible.</p> |
