Thinking about it, amost *all* circuits with switch mode supplies
probably have negative resistance, since they draw less current the
more voltage you feed them with.


yep, they do. thats why an input filter can make a stable smps oscillate.
Likewise driving a smps with a smps can cause problems - Fred Lee's crowd
at VPEC have written dozens, if not hundreds, of papers on this
particular subject.

I think you might find that Middlebrook had something to do with
it....... Mind you I have no idea about the historical perspective.

BTW, who the *** is Fred Lee? Perchance.... does he take Middlebrooks
explanation of the problem and generate shitloads of IEEE papers about
how to solve it with an AVR implementing an appropriate PID controller in
suftware?

Get with it, limey.

OK, thanks....(not really, in the nicest possible way) I did have a poke
about and as far as I am concerned Lee is one of Middlebrooks students.

Anyway, assuming you are an American and at least five hours behind then
it's stil Jiff Lemon Day so go fry one off for yourself.
