    Smps-1200/2500

    Hi,
    This is a project we propose to build:
    1200W - ETD49
    2500W - ETD59

    You archive all the variations below my proposed scheme, but basically you can choose what you plant and how they think of words that will arrange the SMPS.
    From the start we wanted the source can be configured to a certain extent.
    You can choose ETD49 ETD59 or to get up to 1200W or 2500W.
    You can choose Gate driver transformer or integrated.
    Also you can choose to use or SMPS reaction, in fact recommended if you want the look and power supply efficiency to increase by up to 20%.
    You can greatly simplify the source by not using the auxiliary winding and fan control circuit.
    Depending on the desired power you can still connect a pair of diode recovery.
    Also depending on the power to choose the desired EMI filters.

    PCB successfully you up very high currents due to very strong design and very short routes.
    In the picture is not planted fan control module and standby power for tests I used an external source, but now the evening I put up this way and I'll come back with detailed photos.
    SMPS can react or not, has short circuit and overload protection, fan controller and can ON / OFF - REMOTE.
    Fan control is as follows: the source can go home for a few minutes with a predetermined maximum speed resistor, the maximum speed at startup with that role deprafuirea source and verifying the proper operation of fans. After several minutes reduces its speed fans that can be set from a potentiometer. Fan speed increases when the source is loaded with about 100W, if consumption is less than a threshold value starts the fan speed, the fan will continue to operate at high speed for another few minutes, then speed will be reduced, consumption at this time if the source increases, the fan will remain in high speed.
    For high speed fan to start with is no longer necessary to "plant the following components: R43, R44, R45, C44, Q5, DM2, D19, planting these components makes the fan start to be slow, if amps look good HI END.
    We can also provide a large part of the source components, the archive is a pdf OFERTA.PDF "with my constituents, you can buy the whole package or you can just buy the parts you are interested in detail.
    Components "OFERTA.PDF" costs about 30 Euros for a set of PCBs.

    Who would set the whole set of components and boards can benefit from planting all the components of labor supply at a price of 15 Euro for a set.
    Transformer must be material ETD49/59 3c90, if you have high frequency and rapid Mosfeturi choose default 3f3 material.
    To be the primary ETD49 2x11 - 2x12 90/105/120x0 wound with Litz wire, 1mm to get about 7-8V secondary to a spiral if the source has no reaction, if the source has to be calculated appx 6V reaction to a spiral wire must 120X0 be Litz wire, 1mm minimum.
    To be the primary ETD59 2x8 - 2x9 120/135/160x0 wound with Litz wire, 1mm to get about 10-11V secondary from a spiral if the source has no reaction, reaction must be calculated if the source is appx 8-9V to spiral wire Litz wire must be 200X0, 120x0 or two at least 1mm, 1mm in parallel.

    Data for ST-BY power transformer will be made available in a few days.
    For this transformer (ST-BY) will be available in appx 1-2 weeks to a transformer winding for appx 3-4 Euro pretz or ferrite case and the price of 1.5 Euro.

    If someone wants PCBs can offer the prices below, without shipping charges.
    A set of PCBs (PCB 3) = 25 Euro / set
    Two sets of PCBs (PCB 3) = 20 Euro / set
    Three sets of PCBs (PCB 3) = 17 Euro / set

    Excuse the English used is not my native language I used google translate and then I made some corrections ...
    I'm from Romania.

    Smile whooooa

    Nice looking SMPS.


    I cant see the AUX power supply, How do you supply it?

    What driver do you use? do you have some pictures for those SMD PCBS?

    Schemaitc?

    Transformer winding?

    IGBTs or Mosfets?

    Nice any way!

    Hi,
    my Romanian unfortunately is not quite as good as your English. Tried to subscribe to the elforum but failed after several attempts due to my lack of completely understanding. Can you place possibly place the .rar-files in another place easier to access?!
    Thanx, Uli_K.

    Hi,
    Sorry for the inconvenience.
    Now you can have access to all documentation below.

    ==============================

    @ Flyingpig

    I now have answers to all your questions.
    Transformer for IGBT and Mosfet.
    2101 IC for MOSFET.
    2181 IC for MOSFET and IGBT.
    Thanks.

    Hey..


    What about showing us some real load connected to the SMPS 2000W?

    Dummy load? let say? :rolleyes:

    Is this a Resonant SMPS?

    Thanks for the photos..

    Is there any way to get the board file? This schematic is rather massive and trying to redraw it in Eagle or KiCAD is going to put a serious dent in my schedule. Gerbers, PDF, or the straight BRD files would be great. True good engineering costs but open source is a favorite concept of mine.

    Hi Mr DIYAUDIO Romania

    let me understand more about the wiring the transformer.
    what do you mean here

    " To be the primary ETD49 2x11 - 2x12 90/105/120x0 wound with Litz wire, 1mm to get about 7-8V secondary to a spiral if the source has no reaction, if the source has to be calculated appx 6V reaction to a spiral wire must 120X0 be Litz wire, 1mm minimum.
    To be the primary ETD59 2x8 - 2x9 120/135/160x0 wound with Litz wire, 1mm to get about 10-11V secondary from a spiral if the source has no reaction, reaction must be calculated if the source is appx 8-9V to spiral wire Litz wire must be 200X0, 120x0 or two at least 1mm, 1mm in parallel."

    you mean with EDT49 the primary side have 2 X 11 rounds ???
    Cheer

    @ DiyAudio ...in schema electrica transformatorul se leaga intre igbt-uri si apoi pe minus? nu trebuia sa se conecteze la mediana formata de condensatorii de dupa redresarea ~220?

    English:-
    @ DiyAudio ... in the scheme IGBT power transformer is connected between the sites and then the red? no need to connect to the capacitors formed by median recovery ~ 220?
