<p>In an apparatus for driving a PDP, first and second switches are coupled in series between a power source V1 for supplying a voltage Vs/2 and a first terminal of the panel capacitor, and third and fourth switches are coupled in series between the first terminal of the panel capacitor and a power source V2 for supplying a voltage -Vs/2. A capacitor is coupled between a contact of the first and second switches and a contact of the third and fourth switches, and is charged to voltage Vs/2. The withstand voltages of the first and second switches are clamped to the voltage Vs/2 while the voltage -Vs/2 is applied to the first terminal of the panel capacitor. Likewise, the withstand voltage of the third and fourth switches are clamped to the voltage Vs/2 while the voltage Vs/2 is applied to the first terminal of the panel capacitor. <IMAGE></p> |
