A plasma display apparatus is disclosed. The plasma display apparatus a first energy recovery circuit and a second energy recovery circuit. The first energy recovery circuit forms a first energy supply path for supplying an energy to a scan electrode and a first energy recovery path for recovering an energy from the scan electrode. The second energy recovery circuit forms a second energy supply path for supplying an energy to a sustain electrode and a second energy recovery path for recovering an energy from the sustain electrode. Inductance of an inductor positioned on the first energy supply path is less than inductance of an inductor positioned in the first energy recovery path. Inductance of an inductor positioned on the second energy supply path is less than inductance of an inductor positioned on the second energy recovery path.

A method of driving a plasma display apparatus comprising an m-th scan electrode group and an n-th scan electrode group scanned later than the m-th scan electrode group is disclosed. The method comprises supplying a first setup pulse rising from a first voltage to a second voltage to the m-th scan electrode group during a setup period of a reset period, and supplying a second setup pulse rising from the first voltage to a third voltage that is higher than the second voltage to the n-th scan electrode group during the setup period of the reset period.

The present invention relates to an energy recovery circuit of a PDP and a drive method thereof in which the energy recovery circuit uses a booster drive circuit that is able to reduce a sustain voltage by half to thereby reduce the amount of energy consumed by a drive circuit of the PDP and reduce a rise time of a sustain pulse. According to the present invention, a plasma display panel includes sustain means for providing energy to electrodes related to selected cells to effect discharge in the selected cells, and a panel capacitor, wherein the sustain means comprises: an inductor for,charging or discharging the panel capacitor; inductor charge path means which provides a path through which energy is charged to the inductor and is opened when the inductor is substantially fully charged; panel capacitor charge path means which provides a path through which the panel capacitor is charged with the energy charged in the inductor and is opened when the panel capacitor is substantially fully charged; panel capacitor discharge path means which provides a path through which the panel capacitor is discharged and is opened when the panel capacitor is substantially fully discharged; and auxiliary storage means which stores energy if the substantially fully discharged state of the panel capacitor is maintained and supplies the energy to the panel capacitor if the substantially fully charged state of the panel capacitor is maintained.
