existing circuit has power transformer with split coil and 2 diodes. No capacitors. I want to limit the output to 13 vdc. (The output goes up to 17 vdc, burning 12 volt lights). Total current (load) may be 25 amps.
Note: if input voltage < 13 then output must still deliver, may be 1 volt less than input. Output may not shut off. Distributed output vdc is fused.
Wikipedia shows what I expect might work.

Here is the source principle, it can not be altered

I need some guidance as to choosing the right power transistor and may be cooling device.
More background
The diodes will be replaced by type NTE ELECTRONICS - NTE5962 - STANDARD DIODE, 25A, 400V

vdc=volt direct current. split coil = center tap.
thanks
