RE: [TCML] DRSSTC weird waveform behavior

[Justin B <boshjack@xxxxxxxxxxx>]

Well, i put a 10K 25turn pot on it the other night.  I had the pot and inductor in series.  Which was then in parallel to the inductor.  Finally when i turned the pot, i was able to shift the wave.  However, I did not get rid of the ringing. it killed a LOT of it, but not fully.  Also, my current waveform looks like its lagging still.  Maybe its just my CT im using to monitor stuff. it has 250ohm resistor in parallel as a burden.  But it must be centered as the ringing went down.  Another thing i dont get, below i posted a picture of the latest waveform.  Why is my zoom-in version showing very small ring. but the zoom-out version, shows a lot more ring?

I will update this later today when i get time to put stuff together.  I shorted my GDT leads, Twisted them, and did some other mods.  I was told to scope over the decoupling capacitors on the bridge, and see what it looks like, as i may have to do as someone suggested, add dead time.  So I will scope the capacitor for cross conduction  issues..im sure theres some.

Also, that squiggly (didnt work on yet) as i adjust the pot, i can make it be on the top, center, or bottom...The best lowest ringing is where the picture shows it.
