I don't understand your question.
If you mean "capacitors" when you say "caps", I don't know how they
would
deal with output voltage regulation in any meaningful way.

Ditto. ergo my Q. I guess they must in some fashion, just like you
balance
rpc's with caps.

What kind, model and serial number of genset do you have that
currently
has no voltage regulation built in to it?

modified for tri-fuel.

It is regulated, just not to 1 or 2%, a swing of 230 to 250 V, from 50+
amps
down to zero amps.
If you at mid-load it's 240 V, that's +/-10V, which is not terrible, but
it's not 1% either.

Assume no electrical-type regulation at all. There is something between
the
generator itself and the gas engine that ups fuel flow with load,
maintaining a semi-constant voltage. An AVR sharpens this up.

I don't quite understand how this works, and part of the intent of Q was
to
shed some light on this.

I also figgered that if the feedback between generator and engine was
good
enough, AVR wouldn't be needed.
So basically I"m curious about the design of these things.

I thought that it was a possibly that you had heard
of a "capacitor regulator' that I haven't, after 35
years as an electronics design engineer. So I
googled the subject and was unable to come up
with a single circuit/instance where a capacitive
system was used as a regulator....

I have the background to comment on the subject,
so if you will provide a website that comments
on how a capacitor or "capacitive circuit" can
regulate the output of a genset, I will study it
and give you an opinion, which, obviously you can
accept or reject....

I don't post this to insult you, but I really don't
see what you are asking ..

OK.....

I am actually reciting what the company told me.
Apropos of your comment (and Pete's confusion, as well), what I think they
actually meant was that the caps are used to TUNE or balance the system,
somewhat like you would the legs of a 3 ph rotary converter -- which I do
all the time.

As I mentioned above, the "first stage" of regulation is accomplished via
some linkage between the generator and the motor, as in gas powered
welders -- which I've always been curious about how that works.
AVR would then seem to improve this.

Not sure how all this occurs, just exploring the idea of tighter regulation.

Part of my Q was a suspicion that an AVR proly regulates voltage more
tightly, but perhaps at the expense of raw current flow. Iow, I might get
"better" juice, just less of it. Just wondering.....
