    All I can say to you is that mine worked very well and did not burn any components. I have published all the data and also the schematics of the 3 smps I have built so far.

    Cheers Silvio

    Sorry, but when I see this poor layout:

    input_layout.jpg

    a total ignorance of the isolation rules, the choice of a fuse under dimensioned for 1500W, a resistor of 11W while there are techniques to solve the inrush current, layout in single layer ....
    All this is really great amateurism.
    1500W? lol!

    isolation is in the side primary secondary. the fuse is for security only and not affected by big current of output we have a capacitor banc to handle this. 11w capacitor is for having a space for all resistor type and dimention smart man. i had use a 2w resistor and it work perfectly. no problem

    Use fuse 5mmx20mm for this level of current is not conform...
    Voltage level isolation is not conform too in primary side.
    No MOV protection.
    No PFC for this level of power...

    these are basic rules, do a training ... you ignore too much of the essential things.
