12v to 24v converter
12v to 24v converter
(OP)
Anyone have a good print for a 24-28v boost
converter? Application will be for a vehicular
auxiliary 24v system - probably 200 AH or so.
Need ~10-15A max. current for charging.
I'm thinking something similar to:

with a bit more smoke.
Not adverse to building one with F/F drivers, if
I could find one robust enough for the environment,
but the two I have built went T/U after a couple of
weeks.
TIA

the alternator field in the ECM, not with a
standard regulator. And there is not much room
left for an extra alternator in a pickup. :)
If it was not a diesel (with 2 paralleled batteries)
I would replace the alternator and run a tapped
24v system. Lots of reasons not to do it (there
are 2 50-60A intake heaters, electric seats/windows,
fuel heaters and pumps, etc...)
An isolated 12v-12v converter will do it, but
I would like to keep the charge the same on
both series-connected 12v batteries - monitor
circuits here would be added complications.
In the past, I have converted older service
trucks using a 200A, 12v Leece-Neville alternator
which was controlled by an external converter that
ran the alternator at 24v, and had an internal
transformer for the 24v-12v down conversion.
(I believe the original application for these
boxes was ambulances/fire trucks).
But... this stuff is getting harder and harder
to find, and to fit into today's crowded engine
compartments.

It is already ac, maybe 14 volts peak to peak (plus a couple of diode drops). A voltage doubler would come pretty close to producing 28 volts dc output.
