Regenerative power electronics driver for plasma display panel in sustain-mode operation

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 PDP to avoid the abrupt charging/discharging operation. The energy losses due to conventional hardswitching driving and the displacement current of the PDP are mainly recovered. Compared with prior approaches, this driving circuit has a quite simple structure and is suitable for asymmetrical operation
