120 v dc to 110 volt ac

[Lolito]

This is a hypothetical question for anyone who knows the answer.

I am aware that a rectifier is capable of making 120vac into 120vdc, or close after losses, but is there anyway to change it back other than the use of an inverter, or do they make inverters with 120vdc(or other simmilar or higher voltage dc inputs)  to 110 houshold power?

I know that Exeltech still makes a 120VDC inverter   http://www.exeltech.com/

I don't think there is any cheap way.  However, if you make wind turbines,

it might not be too hard to make a Dynamotor.  A motor-generator to make

120V AC at 60Hz but you'd have to regulate the speed to keep the frequency

stable if that is an issue.

it's probably easiest to just find an inverter.  Maybe ebay or similar ?

If you change 120 VAC to DC you will end up with 170 VDC after rectification and capacitor filtering.

Anything that runs on 110 VAC should be completely fine running on 120 VAC

What are you trying to do exactly ?

nothing in particular, I just saw a 30kw servo motor at 90 amps/1500rpm. must be 460 volts or so and I got to thinking that spinning at 300 rpm would generate a lot of voltage. I'm in no position to try any of this out, but I thought it would make a powerful and cheap pma at 200$ plus shipping.

Well, up to a point:  brush-style motors will be fine, but devices containng a transformer won't be doing much!

"Anything that runs on 110 VAC should be completely fine running on 120 VAC"

why would anything with a transformer have issues?

AC is AC ain't it?

Damn, sorry.  I was reading from the subject title ("120 v dc to 110 volt ac").

 Fanman has a high voltage battery bank. He made his own inverter. In one of his postings he said he would tell someone how to build it. I think he said it's square sign wave?

I am very interested to see what a Square Sine Wave looks like ?

or am I missing some humor in there somewhere . . .

 This is the post I am referring to. He has a nice set up. http://www.fieldlines.com/story/2006/2/9/202748/5736
