| 1. A plasma display panel driving circuit comprising:
a panel equivalent capacitor having a first side and a second side;
a first switch electrically connected between the first side of the panel equivalent capacitor and a first voltage;
a second switch electrically connected between the first side of the panel equivalent capacitor and a first node;
a third switch electrically connected between the first node and a second voltage;
a first capacitor electrically connected between the first node and a second node;
a fourth switch electrically connected between the second node and the second voltage;
a first inductor and a fifth switch electrically connected in series between the second node and a third voltage;
a sixth switch electrically connected between the second side of the panel equivalent capacitor and a fourth voltage;
a seventh switch electrically connected between the second side of the panel equivalent capacitor and a third node;
an eighth switch electrically connected between the third node and a fifth voltage;
a second capacitor electrically connected between the third node and a fourth node;
a ninth switch electrically connected between the fourth node and the fifth voltage; and
a second inductor and a tenth switch electrically connected in series between the fourth node and a sixth voltage.
