Rick,
That is an easy solution. But I think you missed the point that I was
attempting to keep my entire system powered by a single 12 to13.8V
storage battery for emergency purposes. Then the task is not quite so
direct. I think the thread was also useful because it makes potential
users of a seemingly acceptable circuit aware that it doesn't perform
to the level expected.
As I mentioned in one of my earlier post, I am pursuing the boost
regulator approach and now have a couple of MC33063AP ICs on order.
I'll provide the schematic to those who have expressed interest in a
circuit after I've had a chance to build it on the bench.
