GDT resources
« on: February 24, 2021, 09:46:31 PM »
Hi again!
I've been working hard on my DRSSTC but now I'm stuck with trying to understand how to build the GDTs. I've read that certain core materials are unsuitable for high frequencies (200kHz for my coil), but I haven't been able to find any equations for determining the how many turns i'll need or what core size I need to use (I suppose it has to do with the necessary inductance of the GDT?).
Any help would be appreciated!

//Jesper

For now, the best resource is properly the archived site here: https://web.archive.org/web/20200120153028/http://thedatastream.4hv.org/gdt_index.htm

also http://www.richieburnett.co.uk/temp/gdt/gdt1.html and http://www.richieburnett.co.uk/temp/gdt/gdt2.html

Mads, what about your GDT for IGBT design calculator spreadsheet (for which I cannot find a link right now)?

It certainly helped me a whole bunch :-)

Thanks Mads!

I'll have do some reading now 8)

I packed this zip in 2017, that must have been the last time it was shared :)
