1-phase to 3-phase inverter

I don't think it can work that way, but I'll look into it.

I was writing thoughts down on the keyboard.  I realize some of what I wrote may or may not work, but the phase shifter I wrote about should work in principle.

Here's another idea:

Take a transformer, connected to hot and ground of the generator, to the primary coil.  One end of the secondary is the output, the other end is grounded.  Use the neutral lead for the other leg of your output as 2-phase AC?
NOTE:
This was a flash of theoretical inspiration.  I haven't tried it in practice.

  I don't know what your budget is but the cheapest way out is get hold of a 3phase electric motor around 30hp.  Then feed the single phase input to 2 legs of the 30hp motor/converter.  From one leg to the dead input of the converter connect a bank of ac rated 3000fmd starting capacitors.  You will need to have a device to disconnect the capacitors once the converter is up to speed.  Also across this bank you will need to connect a bank of permanent capacitors of approximately 400mfd rating.  Once the converter motor is started it will generate the third leg. You will need to derate the horsepower of your 3phase load because the output of the converter is far from balanced. 
  There are also 1phase to 3phase variable frequency drives which will act as both a phase converter and give you the option of slowing down or speeding up your load motors.  They tend to get expensive in the higher horsepower ratings but it will not be necessary to derate your load motors.

Rkhaler , you have some  serious reading to do if you wanna do this yourself.

You will have to understand those high-tech datasheeets or consult an engineer .

If you expect somebody to do it for you on the net then you are seriously mistaking.

@rkahler
dankie is correct.  This is a research forum and personal experimentation is the usually what's practiced, with helpful comments being supplied from Members as required.

Studying further on the subject you have a question about would be the way to go, in my opinion.
