The present invention relates to a plasma display panel, and more particularly, to an apparatus and method for driving a plasma display panel. An apparatus for driving a plasma display panel includes an energy recovery circuit having a first inductor, which is included in a path along which energy is supplied to the panel and resonate with the panel, and a second inductor included in a second path along which energy is recovered from the panel together with the first inductor. Accordingly, a plurality of inductors is serially connected so that an energy supply path and an energy recovery path are separated. It is thus possible to increase driving efficiency without changing a control signal. Further, it is possible to prevent an unnecessary resonance phenomenon by further including a clamping unit.

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.
