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
