What is the most efficient way to produce 24 v DC at 10 amps from 12 v DC?

Virtually unlimited current 12 volt DC supply is available (12 volt/1000Ah
battery pack).

** Go to a solar energy dealer and buy one.

Virtually unlimited current 12 volt DC supply is available (12 volt/1000Ah
battery pack).


** Who needs " most efficient " when there is unlimited current available
??

Got any questions that are NOT stupid trolls ?

1) get a second battery.
2) buy a buck-boost converter made for the real load.

What do you really mean by "efficient"?
Seems a bit silly to talk about power efficiency when you have an
"unlimited" current supply available.

You can buy suitable commercial 12V to 24V converters, that is the
easiest way.

Maybe he has a limited cooling budget ;-)

Agree, though I had success in repairing a MOSFET converter
that was inside a 400W subwoofer amp. Some loser had replaced
a blown 50A 60V FET with a 2A 650V one, probably wondered why
it blew again! This thing generates +-22V, which I plan to use
with a power h-bridge to servo a large PM DC gear-motor that
will drive an antenna rotator for radio DF. We'll see...

The sub-woofer had a large "MOSFET" sticker on it, but the
actual amp used BJTs - the converter has the only MOSFETs.

This 'supply' is solar generated so it is not really 'unlimited' as some
suggest.

If you had the option of purchasing a converter that was 50% efficient or
one that was 90% efficient which one would you buy?

It's amazing how some people just jump to conclusions.

Thanks for the sensible reply's.

Ah, you are the one who first used the term "unlimited".

Right, so it's power efficiency you were talking about. That wasn't
entirely clear in your first post.
BTW, all such devices are going to be switchmodes with efficiency in
the order of around 85-90%
Like this one for instance:

Providing more info up front helps.

So, have you actually looked at the efficiency specs for commercial
ones on the market?
Are they adequate for your needs?

** Shame yours was not a sensible question.

PISS OFF IDIOT !!!!
