| Subject: | Re: EFIS brownout capacitor |
Bob,
Thanks for the Bus-Booster circuit.
I was thinking that an inductor in series with an EFIS would limit the inrush current
to a large capacitor. And when the main battery voltage dropped during
cranking, that an inductor will try to maintain current flow to the EFIS while
the capacitor tries to maintain the voltage. I do not know what size inductor
is required. Inductors are heavy compared to capacitors. It is starting to
look like a small backup battery is the easiest solution to brownout protection.

Thanks John... my alternator is a 40A Denzo 3 wire. It's pretty hard to make
out from the
photos!

Thanks Joe...
That is for a 1 wire, I have a 3 wire... is there much difference?

An inductor would have that effect . . .
but on a scale of weight and volume that
would be exceedingly unattractive.
Yes, batteries are effective energy
storage devices when their weight and
volume are compared with other technologies.
The cost-of-ownership driver for standby batteries
is maintenance. What would be really cool is to
craft a cell technology that might offer a
fraction of the energy storage capability
for popular cells but high longevity numbers.
Bob . . .

pretty hard to beat a couple of D cell flashlight batteries (and a mini
relay) for a couple of seconds of 1 amp 3 volt boost if that is still
the situation being discussed.
One could even leave the batteries in the flashlight so that it can be
used as a --- flashlight.
