Abstract
An apparatus and method for driving a plasma display panel (PDP) where a switch device can perform zero voltage switching in driving the PDP. The apparatus for driving the PDP includes a sustain-discharge unit including first through fourth switches respectively connected to both ends of a panel capacitor between a power source and ground, for sustaining a panel capacitor terminal voltage to be at a first or a second sustain-discharge voltage; a first charge and discharge unit including a first inductor, for increasing the voltage of the panel capacitor to the first sustain-discharge voltage and switching a first switch in a state of a zero voltage by half of a resonance current generated by the first inductor; and a second charge and discharge unit including a second inductor, for decreasing the voltage of the panel capacitor to the second sustain-discharge voltage and switching a third switch in a state of the zero voltage by half of a resonance current generated by the second inductor.
