Patent ID: 8106855

Claim:
A driving apparatus to drive a PDP (plasma display panel), the driving apparatus comprising: a pulse application unit which applies a pulse to the PDP; and an energy recovery unit which comprises an inductor which generates LC resonance with a panel capacitor element of the PDP, an energy recovery determiner which determines accumulation of energy during the LC resonance or emission of the accumulated energy to the PDP, and an energy storage unit which stores the accumulated energy, wherein the energy recovery determiner comprises a first falling switching device which determines the accumulation of the energy; and a second falling switching device which is connected between the first falling switching device and the energy storage unit, in order for the second falling switching device to form a current path through the first falling switching device to the energy storage unit; and a rising switching device which determines an emission of the accumulated energy stored in the energy storage unit to the PDP, wherein the rising switching device and the second falling switching device are directly connected at a node between them.
