1-phase to 3-phase inverter

Try these links. I don't know if it works. I have not tried it.

Let us know how you get on.

Hi rkahler,

  I have been using a static converter on an air compressor and a Bridgeport mill for years now and it works just fine. I got it from McMaster-Carr, it’s on the bottom of this catalog page.

Or you can get one off of ebay they also sell plans.

dude just go on ebay,

VFD drives can take 1 phase and make 3 phase, because vfds take ac turn it into dc, and then it makes 3 phase using 6 igbt fets. It switches the dc back and forth in three different phases.

Thanks, but I need at least 25 HP.

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.

Patent #5,388,031
As a modification, this one has to be turned around the opposite way, but it would be simple.

But, as a concept, would it work as you want it to?  Wiring a transformer to give 2 phases from one signal input can be done, but the ground leg is just 0 volts---no phase to it, right?


I occurs to me that using only the hot side of 3 phases would give you one phase from three.
If you want the total output of the generator, a phase shifter to align the three phases from 120 degrees offset to one single phase would also work.
