A plasma display panel driving apparatus for applying a voltage to an electrode of the plasma display panel. The apparatus includes a first voltage applying unit to apply a first voltage and a third voltage to the electrode, and a second voltage applying unit to apply a second voltage to the electrode. The second voltage is higher than the first voltage. An energy recovery circuit includes an inductor and an over-voltage clamping preventing unit, which maintains a connection node in a voltage range from the first voltage to the third voltage. The over-voltage clamping preventing unit comprises a second diode coupled with the connection node, a third diode coupled with the connection node, and a fourth switching element coupled with the second diode and a first voltage source that supplies the first voltage.
