1. An AC driver for driving an AC-driven member by a predetermined high voltage comprising:

  • a first power source having a first output at a first voltage level;

    a second power source connected to receive the first output of the first power source and having a second output at a second voltage level that is higher than the first voltage level;

    a third power source connected to receive the first output of the first power source and having a third output at a third voltage level that is higher than the first voltage level but lower than the second voltage level;

    driving signal supplying means connected to receive and be driven by the third output and to output a predetermined AC driving signal; and
