[Public-list] inverter

[Meinhold, Michael J]

The Dell Laptop I have at work has a smart transformer that can be
supplied either by 12V DC, or 100-240 AC.
I haven't looked up the AC quality requirements, but I would bet it
doesn't care much.  

I assume you want the inverter for more than the computer, because you
could drive that with 12V DC and avoid all the losses.

Yes, that is exactly what I plan to do. The question is whether my
transformer will do okay with modified sine wave (as opposed to pure
sine
wave) AC power. If so then I can save a pile of money, have my cake, and
eat
it too!

It says on the power supply that it will work with 110-240V, 50-60 hz
(which
means you can use it basically anywhere in the worlds, cuz European and
some
other countries' power is 240V 50 Hz, whereas our power is 110V 60 Hz).
I
figure if it can handle these differences and still provide reasonably
clean
dc to the computer, then it should also be able to handle modified as
opposed to pure sine wave. Am I right about that?
