Spark gap Tesla coils / Re: First coil
« on: July 31, 2019, 09:03:14 AM »
I think they just messed up the formatting, the last paragraph is new and answers (some of) the questions from the actual quote.

Steve Conner tried this (or something close to it) in 2011, without success (http://4hv.org/e107_plugins/forum/forum_viewtopic.php?128784.0). The thread quickly gets away from the topic and moves to experimental tuning modes (the zero in the transfer function and even more unusual things). As I understand it the bad performance is probably due to low ramp quality. Another possibility (loneoceans mentions this in his QCW1 page) is that the primary current envelope doesn't need to be linear. He measured a roughly quadratic envelope with his QCW2 (might be 1.5?), though I recall seeing someone else (Steve Ward?) showing measurements with nearly constant primary current.
Something I'd be interested in seeing would be a 'traditional' buck-modulated QCW, but taking the buck feedback from the primary current rather than the bus voltage. There are probably good reasons why this hasn't been done, I don't have any experience with or proper knowledge about buck converters.

Thanks for uploading it! I had a look at some of the files, the copyright header doesn't look like this is supposed to be on GitHub/public ("CONFIDENTIAL AND PROPRIETARY INFORMATION", and it looks like you forgot to fill in the owner's name)? Is that intended or did you forget to change it?
