The present invention relates to a plasma display panel, and more particularly, to an apparatus for energy recovery of a plasma display panel. According to an embodiment of the present invention, an apparatus for energy recovery of a plasma display panel, which includes front and rear substrates confronting each other, a pair of transparent electrodes provided to a confronting surface of the front substrate, metal electrodes provided to a pair of the transparent electrodes, respectively, a dielectric layer covering both of the transparent electrodes and the metal electrodes, a protective layer coated on the dielectric layer, an address electrode provided to a confronting surface of the rear substrate, a dielectric layer covering the address electrode, a barrier rib formed on the dielectric layer a discharge cell partitioned by the barrier rib, and a fluorescent layer coated on an inside of the discharge cell, includes a panel, an energy recovery circuit charging the panel capacitor using energy charged within an inductor, the energy recovery circuit recovering the energy from the panel capacitor, the energy recovery circuit supplying the panel capacitor with a clamping voltage enabling a potential of the panel capacitor to be constantly maintained and a controller controlling the energy recovery circuit to supply the clamping voltage to the panel capacitor within a period taken to discharge a current of the inductor to a current level higher than zero from a maximum value. Therefore, the present invention advances the charging timing point of the panel capacitor prior to a timing point of discharging the current I<SUB>L </SUB>of the inductor L down to zero or charging the panel capacitor Cp up to the sustain potential Vs, thereby enabling to reduce the charging time of the panel capacitor and to minimize the plasma discharge delay within the cell of PDP. |
