I need to give credit to Mr RB, who posted practically the same idea in this reply.
Thanks for giving me SOME credit!
And seriously now congratulations! You have done a lot of work and got a result to be proud of. It was only a couple of threads back you were working with Colin's converter and you've come a long way.
You still might want to experiment with a much bigger inductor and RC values etc changed to suit. If you can get the frequency down to 20kHz or so the efficiency should be quite nice.
