Abstract:
1. An apparatus for driving a plasma display panel, which includes a plurality of address electrodes, a plurality of scan electrodes and a plurality of sustain electrodes arranged in pairs, and a panel capacitor formed among the address electrodes, the scan electrodes, and sustain electrodes, the apparatus comprising: a first switch and a first diode coupled in series between a first power source for supplying a first voltage and a second power source for supplying a second voltage, a contact between the first switch and the first diode being coupled to one terminal of the panel capacitor; a first inductor and a second inductor, each having one terminal thereof coupled in parallel to the contact between the first switch and the first diode; a second switch coupled between the first power source and the other terminal of the first inductor; a third switch coupled between the other terminal of the second inductor and the second power source; a second diode coupled between the first power source and the other terminal of the second inductor; and a third diode coupled between the other terminal of the first inductor and the second power source.
