<p>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.</p> |
