Have you ever wanted to run a TV, stereo or other appliance while on the road or camping? Well, this inverter should solve that problem. It takes 12 VDC and steps it up to 120 VAC. The wattage depends on which tansistors you use for Q1 and Q2, as well as how "big" a transformer you use for T1. The inverter can be constructed to supply anywhere from 1 to 1000 (1 KW) watts. Important: If you have any questions or problems with the circuit, see the forum topic linked to in the Notes section. It will answer all your questions and provide links to many other (and better) inverter circuits. |

| i want to make a 3kw inverter so can u place the schematic and i also have a doubt is chainging transformers can solve the problem of increasing wattagw or remaning elements has to be changed? | ||
| well, i think that is a good circuit, considering how it's work...but what about the frequency of the output signal, is it properly to use for daily activity? | ||
| If you wanted to output more juice could't one use mosfets instead of using bjt's? Its easy to find 100 amps or more for a fet but not so easy for a bjt | ||
| hi there is it ok to change the tranformer into 220v rather than 120v? coz we use 220v here in philippines..please reply thanks . | ||
| if you cant build one to bad.i build one in 2 hr frome old tv and microwave anonymous the schematic is good you r a asshole iq 0.5 | ||
| If a person would add a pot and ne555 timer could you change the frequency of the inverter | ||
| hello... it is very good schematic i think.... i'm making this inverter thses days but i don't know why my inverter don't work.... is there anyone who have specific information and teach me?? i want to make this inverter... | ||
| Hi, I'm trying to make something like a portable soldering iron and was wondering if it were possible to make an inverter that can run off of a battery pack or small lead acid battery. This would only require about 10 to 15 watts due to its size. For me this is just something to do, a project of sorts, although I don't have any experience building circuits. Everyone has to start somewhere right? thanks | ||
| Hi,
I really like your website. I find looking at the circuits is a bit spoilt by all the pointless comments at the bottom though. (like this one.)
I know most of them are probably from school kids, but really they should still be able to read around the subject, do a bit of research, read your own comments as to the limitations of the circuits, and post appropriately.
Particularly amusing are all the ones that think you're sitting waiting there to instantly design something for them and magic it back to them, or who want you to explain things to them from scratch.
If it were me I'd get rid of most of the comments and, if you want to entertain the kids, enhance the explanations.
Keep it up.
Rich.
(Editor's notes: You would be *amazed* at the ones I don't approve. And just think, I used to get thousands of emails like this per *day*.) |
