Abstract

This paper proposes a novel single sustaining driver with half the device voltage stresses for plasma display panel (PDP). Since proposed driver lowers the voltage stress of sustain switches by series-connected configuration of switches and clamping capacitor between switches, it uses half voltage rating of sustain switches and, thus, reduces the conduction loss of power switches compared with those of the conventional single sustaining driver. Despite device count possibly increasing, by using low voltage switches and capability to produce zero voltage level in sustaining inverter, the circuit cost does not increase compared with the conventional. In addition, the proposed driver has two energy recovery inductors that are utilized to separate the energy recovery path. This feature reduces the power loss of energy recovery circuit (ERC), which gives an improvement in system efficiency. A comparative analysis and experimental results are presented to show the validity of the proposed single sustaining driver.
