Abstract
Voltage pulser circuits are utilized to selectively, alternately supply high voltage to, or ground the high voltage input of plasma panel driver chips. High voltage is supplied to a driver chip only when the driver chip must perform an addressing pulse. The grounding operation, which is induced by shorting the high voltage input of a driver chip to the ground input of the chip, greatly reduces the amount of power which must be dissipated in the driver chip. The use of the voltage pulser circuit also allows full slew rate control of the output pulse which the driver chips supply to the plasma panel.
