Invertor required

I have never seen a vfd that you connect up to a 240v single phase supply to 415v three phase, I am a industrial engineer and have never come across one, I am sometimes wrong though! The only thing I have come across to power up single phase to 415v three phase is a phase converter, there are two types, a static variety which is not a true three phase supply, or a rotary variety which uses motors to generate a three phase supply.
But a vfd? I don't think they exist.

Another alternative, which is often used even on 7kw+ spindle motor applications, and is common in industry where 3 phase is not available or feasible is a transformer to achieve a higher input voltage and a VFD.

I think you will find that the 220v input is 220v three phase, not 220v single phase.

This one seems to be quite specific.
