A crude method is to find three biggish AC power transformers all the
same.  Hook all three secondaries together in parallel, then use one of
the primaries as the primary and hook the other two secondaries
series-aiding to make the 220 volt 'secondary.'  Doesn't even matter
that much what the secondary voltage of each transformer is, as long as
they're identical.  A crude, big, heavy, lossy solution, but workable
esp. since it's not that hard to find three matching 'boat anchor'
transformers at some surplus outfit.
