A regenerative power electronic circuit is proposed to drive a plasma display panel (PDP) in sustain mode operation. This driver utilizes inductors to resonate with the equivalent intrinsic capacitance of the plasma display panel so that the abrupt charging/discharging operation is avoided. The energy losses due to conventional hard switching driving and the displacement current of plasma display panel are mainly recovered. Compared with prior approaches, this driving circuit has a quite simple structure and is suitable for asymmetrical operation. The presented circuit is experimentally verified to be applicable on an 8-inch plasma display panel.
