Patent ID: 7009588

Claim:
A device for driving a plasma display panel having a plurality of first electrodes and second electrodes arranged in pairs, and a panel capacitor formed between a first electrode and a second electrode, comprising: a first switch and a second switch coupled in series between a first power source and a second power source for respectively supplying a first voltage and a second voltage, a common point of the first switch and the second switch being coupled to a first end of the panel capacitor; a third switch and a fourth switch coupled in series between the first power source and the second power source, a common point of the third switch and the fourth switch being coupled to a second end of the panel capacitor; an inductor coupled to the first end of the panel capacitor; and a fifth switch and a sixth switch coupled in parallel between the inductor and the second end of the panel capacitor, wherein a current is supplied to the inductor through a path formed among the first power source, the inductor, and the second power source, and voltages at both ends of the panel capacitor are concurrently changed by a resonance generated by the panel capacitor and the inductor while the current is applied to the inductor.
