I do not understand well how PIXLs performs the automated calculations of the AWG wires in the spreadsheet.
I.e: If I have got a Isrms = 1.735A and for a current density of 9A/mm2 (219 CMA), the mínimum bare copper diammeter for the output will be AWG24 (d=0,51mm, a=0.205mm^2).
That is Ok in the spreadsheet and matches with this criteria extracted from Designing Multiple Output Flyback Power Supplies with TOPSwitch® Application Note AN-22.
So, as it is not recommended to use wires thicker (less) than AWG26 it is needed to use several parallel strands. If I am not wrong with 2 parallel strands of AWG27 (d=0.36mm, a=0.102mm^2) would be enough for that.
But, Why is the PIXIs program reporting an error after filling in the boxes with this information?. The report suggests to use thicker (less) AWG wire or filar.
It can be solved with 6-filar AWG24, but I cannot understand well the reason.
Could you please help me to clarify this? I am interested in understanding well this because it is the key for customizing the transformer designs.
Otherwise I could not develop my design properly.
