Re: Coupling vs secondary voltage chart

The model is running now at 140uS...
If you send me the following data on you coil I can run it. My coil might
be substantially different than yours. The coil I modeled was never meant
to be a DRSSTC.
Streamer length =
Rail to rail buss voltage =
T1 on time =
Current limit =
Max coil power =
If the coil is on your site, which one is it?

I think 300uS is too long of a time to develop a long streamer. So
really, your plots would look much different i suspect at say
100-150uS? Could you test that out and see what it says? In my
limited experience, i find best "long" streamer production to be had
with shorter T1's in the 100-175uS range, but then again, most of my
coils are maxed out at 200uS, after that the sparks dont grow. Now
the question is: is that a characteristic of the streamer, or
something to do with the coupling and tank surge impedance (shaping
the current envelope)?
