Hey Tom.
I've got it wrong about Steve having reduced output with his latest driver,
it turns out that he had increased output in his small DRSSTC.5 coil of a few inches.
All the best with your coiling!

I guess the higher frequency is impacted more by the extra little delay that is added by the 4 or so extra gates. Wow I didn't know a few nanoseconds would make such a difference.

Hey Tom,
Yeah...i've got his latest driver.
i believe that he too had the same problem of reduced spark length when he used his driver in his smallest drsstc,
he put it down to a trait with primary current feedback with small coils?

Hey Mel,
Yes it's very similar except that I used only cmos parts. Well it seems that that must be the problem then huh? Dammit this is bad news, I already started to redesign it again. Is yours exactly like his? As far as it not being a problem on a large coil I don't know. These are the largest coils I have. Damn, I'm glad you brought this up.

The 5v circuit being your latest driver?
but not measuring at the output fets?
20nS delay is quite good!!
Are you powering the fets with 24v?
The 12v circuit has the ucc drivers on it?
ok..no more questions!....lol

The 5v circuit is the slightly older one that im comparing to the newer 12v circuit. The 5v one has ucc27425's but not discrete fets. I guess that wasn't very clear when I said mosfet driver haha. I meant discrete mosfets as a driver. The 12v circuit uses ucc's plus discrete fets @ 24v.
The VHC logic should be about half of what the HC parts can do and the entire CPLD circuit should have the same delay as a single VHC gate.

thats great.....look forward to seeing how your next revised board will function!
its one big learning curve.

Last night I measured the delay in both boards. The 5V one was under 20nS. It doesnt have a mosfet driver on it though. The 12v circuit has a 200nS delay!

hahah well I figured it out. The cmos crap I was using is super insane slow and it was adding a rediculou samount of delay. I'm planning on trying some VHC parts along with a CPLD and some uber fast 3v stuff.
Tab54o 2 years ago
Not all at once. Just thought I'd add that I not 100% sure that's what the problem is but it's irrelevant because im going to be using my older design and then trying another CPLD design as well at both 3.3v and 5v.
