Packing out a bobbin with nylon "wire" to reduce fringing effect heating on transformer coils
I notice power.com DER's often use custom bought nylon served Litz wire for eg PFC inductors, or LLC transformers, Two transistor Fwd transformers etc.
This is expensive and hard to source. Better to use TEX-ELZ would you agree?
To avoid heating in coil due to closeness to the centre leg gap in a ferrite core, simply pack out the bobbin with nylon fishing line...as attached.
What are your thoughts on this?
It means you can use TEX-ELZ instead of that "40 strand AWG28 Litz", which is expensive
