Feneng, the one of the largest professional manufacturers of EFD high frequency transformer in China, welcome to customize !
How is the high frequency transformer wound?
Two things must be noted to make it well:
each winding should adopt many fine copper wires and be wound together, not
single thick copper wire, because high frequency ac has skin effect.
The area is 4.9 mm square, and if 38 pieces of enamelled wire (single section area 0.132 mm square)
with a diameter of 0.41mm are used and wound, the total cut is
The area also meets the requirement.However, the second method has a much larger surface area of
the wire (the first method has a surface area of a single wire cut off)
The surface circumference * the number of shares * the total length of the winding =2.5 * 3.14 * 1 * L=7.85L
Perimeter x number of shares by winding the total length = 0.41 * 3.14 * 38 * L = 48.92 L,
and the latter is the former's 48.92 L / 7.85 L = 6.2 times),conductor
It has higher effective utilization rate, more smooth current, and more flexible
winding because of the soft thin wire. The secondary 75T high voltage winding can
be wound by 3 to 5 pieces.
