High quality EFD transformer with the magnet core and bobbin
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
