Abstract:
An apparatus for driving a plasma display panel having a panel capacitor with an address-driving waveform applied thereto, the apparatus comprising:a first inductor and a second inductor, each having one terminal thereof coupled to both terminals of a path coupled to one terminal of the panel capacitor; a first switch and a first capacitor coupled in series between an other terminal of the first inductor and a first power source supplying a first voltage; a second switch and a second capacitor coupled in series between an other terminal of the second inductor and the first power source; a third switch coupled between a second power source for supplying a second voltage and the one terminal of the first inductor; and a fourth switch coupled between the one terminal of the second inductor and the first power source, wherein the first capacitor and the second capacitor are charged to a voltage substantially corresponding to half of the second voltage.
