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.
