    Hello MicrosiM
    I have nothing to say, but to raise my hat to the great effort you are putting in this site, I have read your reply here and decide to write to you.

    I know what I am looking for is available in the site, but I am a bit lost in here, and honestly I am behind schedule. I am looking for an SMPS design, that can provide 52VDC@16A (so your 1kW RMS will fit), but I can not find the latest design.
    Can you please advise the following:
    1- Where can I download the latest design for your 1kW SMPS.
    2- Hint to how to adjust my output voltage to 52V.

    Thanks in advance

    here is my design for a universal smps, it can use any transformer of etd 49/54/59 and
    input capacitors can be even salvaged capacitors from pc smps. i am enclosing some
    pics of the board i designed. i am not able to included the pdf or pictures.
