Abstract

A new plasma display panel (PDP) sustaining driver using the charge pump technique is proposed. Since this circuit enables low voltage switches to be usable, the cost can be reduced by about 30-40% compared with that of a conventional driver. To recover energy stored in the panel capacitance, a new energy recovery concept of current injection method is adopted to achieve zero-voltage-switching and reduce electromagnetic interference by rejecting the surge current caused by hard switching.
