    • A plasma display has a first power recovery unit including a first inductor having a first end coupled to a second electrode and a second power recovery unit including a second inductor having a first end coupled to the second electrode, the second inductor having an inductance different from that of the first inductor and alternately supplying a second voltage that is greater than a first voltage and a third voltage that is less than the first voltage to the second electrode, while the first voltage is supplied to the first electrode, during a sustain period. A first path between the first inductor and second electrode has a different length from that of a second path between the second inductor and the second electrode, and an inductor on a longer path among the first and second paths has a smaller inductance than that of an inductor on a shorter path among the first and second paths. When the inductance of the inductor on the longer path of the two power recovery circuit paths is set to be relatively smaller, the impedance can be compensated for by the parasitic inductances on the longer path.
