[Milsurplus] transformer

[Scott Johnson]

You are probably much better of finding a single phase transformer, because 
anything you do to connect a three phase transformer to single phase will 
result in severe derating of the transformer, as well as poor regulation (at 
best).  Have you looked around for a switcher?  they seem to be plentiful in 
the 28V/50 A range at surplus places and Hamfests.

Hi all,
            I am building a 28V, 50A power supply. The transformer I have 
was a three phase 208Vac delta input , 20Vac star output. I am hoping to 
connect the input winding to the single phase 230Vac mains here, I seem to 
remember a circuit for converting three phase connections to single phase, 
but cannot locate it. It's for a mil project. Does anyone remember the 
circuit?
             Regards, Brad
