    How to know parameters of existing SMPS Transformers ?

    The winding in it and it's pinout doesn't or will not correspond with your amps layout. The awg of the primary and secondary may not be what u want, base on the components value for ur smps moreover in order to do so, u will need to know the output voltage, and current, effective cross sectional...

    400w current-mode boost UC3845

    i think feedback is not working properly use TL431 with octocoupler(PC817) it will regulate it well

    Ir2153 1000V floating voltage problem

    Pls can someone tell me how to solve the problem my ir2153 smps produce more than 1000V from the output at least that's what multimeter show me and when I connect a led on it nothing light up, I don't understand what kind of voltage is that my Np was 2x15 turns while the Ns was 2x6, at first I...

    Output current problem

    Thanks so much for the detailed explanation, I think the chip is a fake as you said, we in Nigeria are suffering in the hands of the Chinese as they flood our country with substandard products once again thankyou so much

    Output current problem

    Hello Mr Silvio its a good evening in my country now, how are u thanks so much for the previous help and the explanation u gave to me. I have build ur 700watts smps, but to my disapontment it refuse to start up , I use 11n60, irfp450, irf740 the voltage at the vcc of the ir2153 is 10 volt is...

    Output current problem

    am very sorry please then where is the primary of the current wind at? or the current sensor transformer does not have primary? how will voltage be induce in the secondary of the current transformer? its not very clear to me please

    Output current problem

    sorry i still cannot get it right, it seems from the picture after i have finished winding the Primary, secondary, auxiliary 1 and 2 then will now wind 2 turns the connect the 2 turn loop to the bta12 then the 80turns will now be connected the two zener diode that form the full wave...

    Output current problem

    sorry to bother u so much am trying to built your 700watts smps, as per your schematic there is a two point that you specify as TO 2 TURNS LOOP TO TRAFO from the triac BTA12 CAN U PLEASE EXPLAIN WHERE THAT WILL BE CONNECTED TO? thanks in advance
