There are numerous commercial DC-to-DC convertors available (we use the Vicor
brand extensively). These things are pretty remarkable in that they will
deliver a rock solid output voltage, even at their max rated current draw,
while the input voltage varies over a factor of 3 or more. They are also
amazingly compact.
