    Good nigth vorezky
    Diagram and PCB are in page 3 of this thread.
    SMPS are HARD TO BUILD AND DANGEROUS.
    Please read other topics of this forum before start something.

    Best regards

    Hi to all;

    I'm just a newbie in smps design and this thread inspires me alot of building my own. I want to start building this project but with different dc voltage output 12vdc 40Amps, 24vdc 20Amps. I know it needs TR1 recalculations which I started doing now. I just want to know if Epcos E42/21/20 is just right for this circuit.

    Many thanks.

    hi gio, may I ask about your 800watts smps at the first project with ir2153. now I have started to build smps based on your scheme, I'm just confused about power source that you used. thats came from 220 AC volts or 127 AC volts.?.. or anybody in this forums can help to solve my problems.?...

    thanks before...

    Here is schematic, copper side of smps.
    Also some pictures of the amp fully working (not finished yet) but fully tested four many hours in many usage conditions.

    Enjoy it
    Hi,

    I'm new to the forum but already I see some great minds here. My passion are SMPS's and amps as well Great job giololucas. I started my first project after a long time of absence from this field and this SMPS looks really good. I was thinking in using L6599AD from SGS as well. Anybody has experiences with this one? In the past I used SG3525/26 and it worked. But I wanted to move forward. Also if anybody can suggest a good, stable Class D amp that can deliver some power I would be very gratefull.

    Thanks and it is nice to be apart of this community.
