    i have a sonimat gm 2010 power supply that is supplying an ultrasonic welder that welds nonwoven materials.
    i want to build a circuit to replace this power supply.
    the output is 20khz in 800 to 1000 volts ac.
    can anyone give me a circuit? :confused:

    Before even beginning to answer this question I have a few for you...

    First and foremost have you ever worked with voltages like that ever before (better yet have you worked with standard mains voltages before?)

    If the answer is no to those just stop reading right there....

    If yes then we still need to know more,

    What currents do you need?
    What is the voltage/frequency tolerance?
    Switchable from 800-1000 or does it need to ramp?
    What is the voltage/frequency of the mains?
    Have you looked into replacement prebuilt power supplies? (probably cheaper)

    there are more but lets start with that

    yes i have worked with high voltages.
    ferequency tolerance is 20000 to 20100 hz.
    mains voltage is 220 50hz.
    output voltage is 1000 volts.
    yes i have looked for other supplies but didn`t find the match.

    I have to ask the obvious, have you contacted Sominmat about a replacement?
