SMPS transformer winding?
« on: January 26, 2024, 07:41:20 am »
Hi,
When you are eg winding a PQ26/20 bobbin, it's a vertical bobbin so (if its a single layer) you have to start and terminate the windings to the same end of the bobbin.
So , if you need to wind say three single layers ....then how do you get the coil end "back across the bobbin" for termination?
Do you...
1....Suddenly stop the coil at n=x turns, and then do a right angle turn down across the bobbin and terminate?
2.....Spiral wind the last turn back across the bobbin so you can terminate it?

PQ26/20
