Holcomb Energy Systems:Breakthrough technology to the world

[both Micsigs - STO1104C transfer very
large files to the PC program so they
need some work to reduce and still be readable]

LC him with a picture of my 2 smartscopes - just kidding!}

Attached: pdf (we'll see if this works) (sorta!) 

While I'm here - Note the N1-4 S1-4 coils use mostly recovered FB for power,
thus the LAP forms the output (as shown in shot 1)- its a 2 stage system so to speak.

For the FlyBack (FB) trolls - the FETs are SiC driven from an 800MHz processor directly
from the internal timers (dv/dt).

Much nicer for bad eyes.  Yes, I can see it clearly now.

Dang SL, remind me to never play poker with you.  How long have you been holding
those cards?  I mean seriously, you were only talking about laser cutting just a couple
of weeks ago.  You have a whole team working on this device or just can't sleep?

You're switching at 8ms, giving an output frequency of 125Hz?  And for units, those are
actually Volts and Amps, not milliamps?  Milliamps are on the input side right?  Holy smoke,
that little thing cranks out the juice.  Would certainly charge a cell phone without issue.

Looks like to me you are recovering all the back EMF, plus getting output from the LAP,
is that correct?  The phasing isn't perfectly lined up, but there is definitely a good amount
of overlap, enough to do real work with.


That's some awesome results SL.  Nice work.


Curious, do the end nodes show slightly less output than the middle nodes?  Being
a linear generator instead of circular, I would think the middle transitions to perform
slightly better.

These are current traces from 2 identical inductances in a Ltspice sim. The green trace I(L1) is a 12V 1ms pulse. The yellow trace I(L2) is the flyback. Interesting is that the current pulses begin 1.03ms apart, and the max amplitude is only 0.03ms apart, with almost the same amplitude.

It looks to me like the flyback could power the neg pole coils at almost the same time as the pos pole coils.

I guess this post makes me an official (FB) troll. LOL 

Is this anything like what you are doing SL?
