Question about VFD

I am looking for a single -> three phase. I have looked at Invertec drives, but haven't found one in the U.S. that will fit my needs. 115-220 single in, 220 three out, 2 HP. I did find a KB Electronics KBDF-27D that fits the bill for a really reasonable cost. We have KB VFD on our portable pumps at work and they have run fine for about 4 years now. I haven't decided yet I'm still looking.

My understanding is that most 3-phase drives are capable of running a 3 phase motor off of single phase. Provided the drive doesn't have a safety that shuts it down when a phase is lost. The GS2/3 drives from Automation direct would work and a quick google search brings up lots of hits.

If you can live with the same voltage out as in, then almost any VFD will work.

Ones that double the input voltage exist, but are much rarer.

It is possible to re-arrange the input stage of a VFD to double the voltage. (re-configure the rectifier as a Delon circuit: en.wikipedia.org/wiki/Voltage_doubler#Delon_circuit ) so that you can run a 400V motor from a 400V VFD on a 240V supply.
