most of his posts about magnetics are flat wrong.
You're an idiot. My remarks about gapping switcher transformers is
correct. We aren't talking about millimeter gaps here. More like nil
gaps. They have their function, and you would be wise to learn what
that function is.
However he has posted some useful stuff about HV windings.
The most common mistake made by folks experimenting with small
scale, high ratio step up, high turns count HV transformers are
placing too many turns in a given secondary segment, allowing a breech
through the insulation of the mag wire. Even the best double thick,
high temp mag wire is only good for about 300 turns per segment.
If one is not using a multi-segmented bobbin, one should place
layers of tape between a certain number of turns, and another "set" of
turns to keep the lowest voltage turn(s) away from turns that are at a
much higher voltage.
Volts per turn can be calculated to give the builder an idea of
where to "layerize" his turns or step to the next bobbin segment.
This is why a lot of Tesla coil builders space wind their stack
coil. Depends on how well they have designed it though, really.
A good double strength mag wire, and even varnishing of the finished
stack is always a good practice (several coats). I know this, and I
have yet to build one.
I will though. I'll use it to reproduce myself (ala prestige) and
send my double over their to whoop up on your lack of gapped core
knowledge. Slap ya right in the face. Tee Hee Hee!
