    Hi All,
    I am interested in making an generator for
    high power (50-100W) industrial ultrasonic transducers.
    I believe the capacitive load is 5200pf, Vpp ~220V.
    Freq : 28Khz (squarewave)
    In intend to generate the 28kHz with a microproc (AVR?)

    I read that one can drive this with hi-freq step-up transformer.
    I have no knowledge on high-power/hi-freq transformer
    design as may be required for this application.

    I know one can buy self-osc generator scheap-cheap from China.

    I would like to make my own though.

    Regards,
    GjL
