--- Quote from: imo on August 06, 2018, 09:52:22 am ---Partially off topic: In mid 80ties colleagues of mine did simulation of sub-micron GaAs semiconductor devices on an Sinclair Spectrum with 48kB ram and Basic. They did PhD with such an gear. Moral of the story - it is not about the gear but how a) good/well you can describe the stuff by the "theory of electromagnetic fields" and how b) good/well you can built a "system of differential equations". PS: today the diff eq solver for b) is fortunately ready to get off-the-shelf.. (Spice) :) --- End quote --- Hello imo, The problem I have is that with spice softwares (I'm using LTSpice), I'm able to simulate the IEC 61000-4-2 test and produce a current waveform really accurate to the real one. But now, after producing this waveform, I'm not that able to check how the spark gap is going to behave depending on the distance. I'm trying to simulate it but the circuit, as other members have said in upper comments, it is not acting as it would in real life. btw, thanks for your tip! |

How did you end up simulating the spark gap? There's an LTspice model of a triggered spark gap https://hofstragroup.com/triggered-spark-gaps.html but not sure whether it's applicable to this situation. Were you able to use LTspice in the end or did you have to resort to fancier tools? |
