UD2.7 onwards - post-2014 changes published anywhere?
« on: November 29, 2022, 07:32:37 PM »
If anyone could point to where schematics for versions of UD2.x post-2014, I'd be interested to  dig in.  I don't mean the change of tactics with UD3 --aware of Netzpfuscher's and other's work -- but somewhere in its evolution before coding became involved.

I know Lone Oceans (Gao Guangyan) catalogued 2.7C very comprehensively in 2014; that seems to be the last open-source work on late 2.7+
 pre-UD3.x versions. He noted  the contributions of Eric Goodchild & Bart Anderson through the evolution from Steve Ward's foundation design, as well as his own.

Someone I was in comms with sent me photos of a post-2014 board a few years ago.  I never found out the provenance of it & we have lost touch.  Among other differences from 2.7C, I did find a note from visual inspection --

*Shorting jack for phase lead adjustment eliminated
*C33 in D2.7 (part of hysteresis loop for TL3116) becomes C25 in this later version
*Chassis-mounted LED's become part of board population
*PCB was built for the two channels (logic and gate drivers) but board wasn't redesigned, simply entire CH2 left unpopulated
*Overcurrent pots. mounted vertically on PCB

I can't see there was any substantive possible improvement from 2.7C, so I'm curious what was actually done that isn't cosmetic in 2.7+ versions  Were there any known glitches remaining after 2.7C?

Did you check out the prof9dc PCB pack? It has UD2.7 and UD2.9 (pulse skipping)

Besides UD2.9, there are at least two other pulse-skip offshoots of UD2.7 that use simple logic chips:

Not certain if that is exactly what you are looking for.

Mads, yes, great resource there.  Seems like there’s a big jump shift of approach  between 2.7x and 3.  I think I’m probably looking at a place of record for subtle 2.8ish revisions.  Things seems to have been jazzed up  in what looks like a significant way on that path.  Great to see what happens when imagination meets EE- where will we go next?

Dave, pulse skipping,2.9 looks really interesting and I wasn’t aware. Will dig in and see if I can retrofit .

Thanks both
