You would think this would be easy to find.
« on: August 17, 2019, 09:01:00 PM »
Been looking at driver boards, some have a feature of arc Extinguishing some say digital arc extinguishing. Doing a google search tell you nothing. So I have a question again

With the driver board do I have to have an interupter and is a interupter just for music and what is arc extenguishing feature. I know what arc extengusing is on spark gap, but on sstc what does it do.

Would this be close to correct.   Need power supply for the igbt, need the driver board to fire the igbt. What is the frequency limit of the  UD2.5 driver board. Just trying to get a simple block diagram of sstc in my brain. This is going to be next prodject. So much info and bad info it really is making me pissed.

My opinion is that you should start out simple and then improve/make your system more complex. This way you can learn a lot more than by building an UD-kit coil.

With the driver board do I have to have an interupter and is a interupter just for music and what is arc extenguishing feature. I know what arc extengusing is on spark gap, but on sstc what does it do.

If you want to build a sstc (one resonant coil) you probably dont need an interrupter (most designs dont, but some do), with a drsstc (two resonant coils) you probably do need an interrupter.

A use for an interrupter is the music functionality. Other uses of interrupters can be to limit heat production in sstcs. For drsstc you have to have an accurate interrupter, which can vary the ontime and not just the frequency.

Arc extinguishing is probably the detection of groundstrikes and then an interrupter pulse, to kill the arc and prevent excessive current draw. The UD2.X doesn't have this feature and it works good enough.

Have a look at this diagramm from the book: DRSSTC BUILDING THE MODERN DAY TESLA COIL

The diagram isnt perfect (like the feedback is commonly on the primary) but it should give you a good idea.

btw I can recomend the book for further reading, also you might want to check out mads drsstc and sstc design guides, or loneoceans sstc II guide.

Thank you Thank you. This is what I wanted to know. Thanks

So  when the time comes, I can replace the syncronous spark gap with the solid state stuff and use the same primary and secondary. I though I had read that the solid state drivers would not work at the higher khz like 100khz or above so I would have to start over, the one I am building now is 125 160 khz some where around there. So this driver box will pulse at the frequency that I want.

This will probably be next year, if I start now. Thanks again. By the way what is a ud coil kit.
