Abstract
In an energy recovery circuit of a plasma display panel, after storing energy in the inductor, the panel capacitor is charged by using a resonance and the stored energy. A first time period during which energy is stored in the inductor before discharging the panel capacitor is longer than a second time period during which energy is stored in the inductor before charging the panel capacitor, so that a voltage higher than half of the sustain-discharge voltage is charged to the energy recovery capacitor. In addition, the first time period of the case in which the load ratio is low is shorter than the first time period of the case in which the load ratio is high, so that the thermal stress applied to the energy recovery circuit may be reduced.
