A special energy recovery-sustain driving circuit system is proposed to drive a shadow mask plasma display panel(SM-PDP) efficiently. The operational principle of the proposed system is presented with theoretical analysis. Some methods to drive metallic oxide semiconductor field effect transistor(MOSFET) are introduced. The system uses the series resonance between the inductor and the intrinsic capacitance of PDP to realize the energy recovery by lowering the capacitive displacement current of the PDP. The validity of proposed circuit system is verified through its successful application in the 34-inch-diagonal full color SM-PDP.
