secondary turns. The typical transformer will have a 1:1 turns ratio for a power
MOSFET, and may be less that for a bipolar power transistor.
For dc input voltages that are more than 100VDC, a layer of Mylar tape
should be placed between primary and the secondary(ies) and between any mul-
tiple secondaries. One should not completely trust the insulation breakdown
voltage rating of the magnet wire since it could nick during the winding process.
3.5.9Winding Techniques for Switchmode Transformers
The physical winding of switching power supply transformers is very important.
It can make the difference between a switching power supply that is excellent ...
