number of strands???
I need to know the size of litz strands in SMPS Transformers because i've found that the size cannot exceed 0,07mm thick, that way I will have to use a huge number of strands, but that will affect the current, the resistances.....
Litz wire is used to achieve highest Q. For high frequency magnetics the litz wire is great for low voltage/high current windings, although multiple strands of medium gauge enamelled wire are enough.
So, in order to decide litz wire or multi-strand is helpful to know the AC resistance increment of a specific wire diameter.
Hope it helps.
