Using a large transformer. A **really** large transformer.

Given that, you will have to be drawing around 5 amps dc just to get half an amp at high voltage given that you have a perfectly efficient system. (not even close)

So saying you can come up with all that it's just a matter of looking up what wires go where.

A far more practical approach is to find how low of a voltage your motors can run at and still give results.
