Abstract
A sustainer for an AC plasma panel is disclosed, wherein two MOSFET transistors are used to alternatively, selectively provide a two level output signal which is used to maintain the emission of light from the plasma panel. The sustainer circuitry requires only a single logic input to control both transistors, and prevents both transistors from conducting simultaneously. The slew rate of the sustainer output is controlled to prevent noise generation, and circuitry is included to prevent high frequency oscillations in the transistors.
