Re: [TCML] Turn-to-Turn short circuit

[Stephen Hiscock <stephenhiscock@xxxxxxxxx>]

I'm assuming you are talking about a single layer inductor? and the 
wires are all touching each other? and they are all insulated?
(if not insulated then you will have to work out the insulation of air 
for the gap between turns that you have)

It depends on Voltage per turn (ie what is the final output voltage 
divided by the total number of turns),
The insulation of the wire ie what voltage will produce a discharge 
through the insulation of surrounding each individual wire,
and how far apart the overlapped the overlapped wire are from each other..
eg you could have 20 wires overlapped if the over lapped wires are only 
overlapping one at a time and are all spaced far from each other.
but if all next to each other, then it may be problem

But saying this simply, if the Voltage per turn exceeds the wire 
insulation then you will have a problem ,but 99.99% of the time this 
won't apply.
