Up to ~1.5hp you can buy 115v input VFDs that output 220v. I think they just use voltage doublers in their rectifier stage and 2x the capacitance.
FWIW, these DON'T work well in a (properly wired) garage. 120V outlets in a garage are supposed to all be GFCI protected. Motor frame leakage currents will trip the GFCI when using a VFD:( 220V outlets are not GFCI protected.
