1-phase to 3-phase inverter

[rkahler]

I need inverter with 1-phase input and 3-phase output.
Can somebody make a suggestion ?
I tried Google, but I'm lost in all high tech datasheets.

@ rkahler

One way to do this is to use a 3 phase electric motor and connect 2 of the lines to single phase then use the 3rd line as the supply for the 3rd phase.

This is not a very efficient way to do it but it does work.

Thanks, but I don't like this idea.

I'm working on generator that will give me a single phase at the and.
My main load will be electric boiler which is 3-phase and I would like to be able to run it with that generator.
Further more, I would like to replace input for all 3 phases in my house.

Check out http://en.wikipedia.org/wiki/Inverter_(electrical)....

Look at the section marked 'Three phase inverters' for a simple circuit. The only problem is that it is missing the triggering circuit.

A different way to make 3 phase energy is to modify a distributor.

I made dc to 3 phase-pure sine oscillator, It was ALOT of work and alot of $ developping it .

But right now I have no $ to buy the components and release my product . I am saving up @ my day job , hopefully I will release soon and sell on ebay .

It will be expensive however , it will be rated for low power usage also , 125w to 200w maximum per phase . I feel that you are trying to run a wind turbine of some sort and turn that into 3 phase , my thing will not be good for that .

I think you can find schematics for  a single phase to 3 phase, or purchase one .
