Apparatus and method for driving plasma display panels
An apparatus for driving a plasma display panel that includes first and second signal lines for supplying first and second voltages, respectively, and first and second inductors coupled 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 drop the voltage of the panel capacitor from the first voltage to the second voltage. A second current path is formed to recover the current flowing to the second inductor towards the first signal line, while the voltage of the panel capacitor is sustained at 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, to raise the voltage of the panel capacitor from the second voltage to the first voltage. A fourth current is also formed to recover the current flowing to the first inductor towards the first signal line, while the voltage of the panel capacitor is sustained at the first voltage.
