Device and method for efficiently driving plasma display panel

A system for driving a plasma display panel according to a switching sequence in which a reset period, an address period, and a sustain period repeat, the system comprising:

• an Y-electrode sustain driving circuit dividing charging and discharging modes, which are executed to apply a high-frequency square wave voltage to Y electrodes of the plasma display panel during a sustain period, into first and second charging modes and first and second discharging modes, respectively, forming different resonance paths, which pass different inductors, for the first and second charging modes and different resonance paths, which pass different inductors, for the first and second discharging modes, and driving the Y electrodes of the plasma display panel to be charged/discharged;
• a separating and reset circuit separating a circuit operation during the sustain period, a circuit operation during the address period, and a circuit operation during the rest period from one another and applying a lamp-type high-pressure voltage during the reset period;
• a scan pulse generator applying a horizontal synchronization signal during the address period and being short-circuited during the other periods;
• and
• an X-electrode sustain driving circuit dividing charging and discharging modes, which are executed to apply a high-frequency square wave voltage to X electrodes of the plasma display panel during a sustain period, into first and second charging modes and first and second discharging modes, respectively, forming different resonance paths, which pass different inductors, for the first and second charging modes and different resonance paths, which pass different inductors, for the first and second discharging modes, and driving the X electrodes of the plasma display panel to be charged/discharged.
