Novel regenerative sustain driver for plasma display panel

A novel sustain driver is proposed to drive a plasma display panel (PDP) while minimizing circuit complexity compared with prior approaches. The presented driver uses an inductor to resonate with the equivalent intrinsic capacitance of the PDP so that abrupt charging/discharging operation is avoided. The energy loss due to conventional hard switching driving is mainly recovered. All active switches are operated with zero voltage switching and all diodes are turned off naturally without the problem of reverse recovery.
