In an address driving circuit including a power recovery circuit, the voltage of the address electrode is reduced through a transistor, and the voltage of the address electrode increases through the current formed by the body diode of the transistor. In addition, the ground voltage is not applied to the address electrode in the power recovery circuit after the voltage of the address electrode is reduced. As a result, the resonance for raising the voltage of the address electrode and the resonance for reducing the voltage of the address electrode can be performed through the same transistor, and the transistor for applying the ground voltage to the address electrode can be eliminated.

A method and apparatus for driving a plasma display panel (PDP) by which reset stabilization can be achieved are provided. In the method for driving a PDP, successive field periods, each including a reset period for initializing the state of respective cells, an address period for selectively discriminating cells to be turned on from cells not to be turned on and for performing an addressing operation, and a sustain period for discharging the addressed cells are performed. A reset stabilization period for inducing discharging in a discharge space between cells is additionally performed before the reset period if a rest period having a predetermined time duration is present between the sustain period of a preceding field and the reset period of the field. Therefore, the reset operation can be performed in a state where discharge cells between electrodes are sufficiently primed.

An apparatus for driving a plasma display panel includes a first signal line and a second signal line for supplying a first voltage and a second voltage, respectively, and a first inductor and a second inductor being to one terminal of a panel capacitor. A first current path is formed from the panel capacitor to the second signal line via the second inductor to reduce a voltage of the panel capacitor from the first voltage to the second voltage.

A third current path is formed from the first signal line to the panel capacitor via the first inductor while the current flowing to the second inductor is recovered, thereby increasing the voltage of the panel capacitor from the second voltage to the first voltage. A fourth current path is formed to recover a current flowing to the first inductor to the first signal line, while the voltage of the panel capacitor is sustained at the first voltage.
