Abstract
A drive circuit for driving a plasma display panel (PDP) includes a pulse voltage generator that contains main switching elements disposed on a high voltage side and on a low voltage side, is operable to generate a pulse voltage by operating the main switching elements in accordance with an output voltage from a first power supply and apply the pulse voltage to a PDP scan electrode and sustain electrode, and a reset voltage generator operable to generate a reset voltage in accordance with an output voltage from a second power supply and apply it to the PDP. The pulse voltage generator contains a first diode that prevents the voltage output by the reset voltage generator from being applied backward to the first power supply and a first switching element connected to the first diode in parallel.
