    摘要: A plasma display and a driving device therefor. In a sustain discharge driving circuit that includes a power recovery circuit and a sustain voltage supply circuit, a transformer is used. The transformer includes a primary coil and a secondary coil that are coupled with each other. The primary coil of the transformer is connected in parallel to a panel capacitor serving as a capacitive load so as to increase a change of a voltage that is applied to an inductor, such that a voltage rising period and a voltage falling period are reduced. With the reduction of the turn-on time of a switch, the power consumption of the switch is reduced. Further, as the inductor initially stores current, the occurrence of hard switching is reduced when a sustain discharge voltage is applied and elements of the circuit are protected.
