Abstract
A PDP driving apparatus includes a sustain discharge unit including a first switch and a second switch connected between a first voltage and second voltage and having a contact connected to one terminal of a panel capacitor, and a third switch and a fourth switch connected between the voltages and having a contact connected to other terminal of the panel capacitor, for maintaining either terminal voltage at the first voltage or the second voltage; and a charge/discharge unit including a first inductor and a second inductor connected to the terminals of the panel capacitor, for boosting a current to a level to store energy in the first inductor and the second inductor while either terminal voltage of the panel capacitor is maintained at the sustain discharge voltage, and inverting the polarity of either terminal voltage using the stored energy.
