Abstract: | A novel sustain driver employing an energy recovery faculty is proposed for efficient driving of a plasma display panel (PDP) in the sustaining mode operation. The proposed driver uses dual resonance. One is a main resonance between an inductor and an external capacitor to produce alternative pulses and the other is a subresonance between an inductor and a panel to recover the energy consumption by the capacitive displacement current of the PDP. The operational principle and design procedure of the proposed circuit are presented with theoretical analysis. The validity of the proposed sustain driver is verified through the simulated and experimental results based on a 7.5-in diagonal panel with 200-kHz operating frequency. |
