High quality PQ high frequency transformer with PO2020 bobbin
Do you know how is the high frequency transformer wound?
Two things must be noted to make it well:
One: 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 so-called skin effect, simply put, is that high frequency ac only walks along the
surface of the wire.The inside of the wire does not run current
The weaker the axial current in the wire, the closer it is to the surface of the wire,
the stronger the current is.The use of multiple strands of thin copper wire and winding
together, is actually to increase the wire
The surface area of the wire, thereby making it more efficient to use the wire.For example,
the primary 3T+3T, if you use a single enamelled wire with a diameter of 2.50mm, the
cut of the wire
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.
