Transformers are made to do just that.

Figure your load and size accordingly then get a unit with a 208 volt primary and a 120/240 volt secondary.

If for example, the load figures out to need a 5KVA unit, the Square D model would be 5S7F. It has a 208 primary and a 120/240 secondary.

Other manufacturers will have the same unit, I just happened to have my Square D book handy.

Square D has then from 1KVA up to 167KVA.
