For US-based systems, [Of undoubtedly several] one abbreviated discussion is:
It may be worthwhile to peruse manufacturer’s literature for suggestions. Clearly, for your application their literature will tend to point to more-sophisticated assemblies, but some seem to have addressed specific, related needs and claim to have a track record for serving this type of industrial machinery.
In the US, typical utility character-of-service boilerplate may be: “Three-phase… service may be provided to a single-family residence for… use at nominal voltages of 120/240 or 120/208 volts at [our] discretion… [initially] billed to the customer to recover the costs of supporting three phase service… "
The other, possibly significant financial outlay is a [non-utility-furnished] transformer bank at the converter output, that would likely be something like a 220∆/380grdY configuration. Depending on ready availability, it may be fashioned with a set of 1ø units by a qualified, experienced installer. Depending on served-equipment power demand and voltage tolerances, an autotransformer bank may be cost effective. Phase conversion with integral voltage transformation is likely hen’s teeth.
It seems like in a number of regions, availability of acceptable 3ø power is impossible or prohibitively expensive. A lot seems to do with utility-rate structures, [zoning for some] and line-extension/facilities-upgrade costs associated with existing, localized line/transformer accessibility.
“Ask questions of several before you buy.” Detail your expectations in writing. The ‘shopping’ process may seem a bit daunting, but probably not impossible. As mentioned, the need for a stiff 1ø service complicates the matter to a degree. Discuss equipment and related “system” aspects—id est, utility-service+disconnection/short-circuit/overload-protection+wiring+converter+transformer+machinery characteristics and specifications with potential vendors, with the clear objective that you need a complete, readily useable, acceptably operational system—fully compatible with your electrical service and served load. {You may want to allow for a degree of later “expansion.” } Consider equipment enclosure withstand of materials like dust, coolant and metal particles. Realize that such equipment may affect things like overall building voltage regulation for motor/converter starting and running, space availability, maintenance needs, site noise level and heat load.
For the cited class of equipment, the advice dispensed in “rec.hobby.*” newsgroups is probably best given little credence.
