Abstract
A plasma display panel with a driving apparatus including an inductor of which one end is electrically connected to one end of a panel capacitor. The driving apparatus of the plasma display panel alters a terminal voltage of the panel capacitors into a second voltage by storing energy in the inductor using energy of the panel capacitor charged with a first voltage. The terminal voltage of the panel capacitor is changed into the second voltage, and thereafter, it is maintained at the second voltage by freewheeling current flowing through the inductor. In addition, the terminal voltage of the panel capacitor is changed into the first voltage using the energy stored in the inductor. The terminal voltage of the panel capacitor is maintained at the first voltage by connecting one end of the panel capacitor to a first voltage source after it is changed into the first voltage.
