A new sustaining driver for a plasma display panel (PDP) employing a gas-discharge current compensation method is proposed. It features a high performance, zero-voltage-switching, high efficiency, low EMI and high energy-recovery capability. Furthermore, since it compensates for the large gas-discharge current, it enables the PDP to light at a lower voltage than the prior circuit. [ABSTRACT FROM AUTHOR]

A new zero-voltage and zero-current switching (ZVZCS) energy recovery circuit (ERC) for a plasma display panel (PDP) is proposed. The external current source ensures the zero-voltage mm-on of all MOSFETs, zero-current tarn-off of all IGBTs, and fully charged/discharged PDP, which desirably reduce the sustaining voltage. Moreover, it features simpler structure, fewer devices, lower cost, lower electromagnetic interference noise, and lower current stress. [ABSTRACT FROM AUTHOR]
