well, you could put a 3.8 ohm resistor in series with a diode. The output would have a lot of ripple and the resistor would need to be rated for about 30kW.

I think you need to be a little more specific about what this is for, or define the line/load regulation and ripple allowable.

It's a non-trivial request.
