Novel energy-recovery driving circuit for plasma display panel using regenerative transformer

A novel energy-recovery driver is proposed to efficiently drive a plasma display panel (PDP) in the sustaining operation. The proposed circuit can achieve zero-voltage switching (ZVS) for clamping switches and zero-current switching (ZCS) for resonant switches and diodes for all modes of operation. The charging/discharging energy of the panel capacitance can be recovered through the regenerative transformer without additional components.
