I'm getting a growing interest in distributing power with component
arrays. R's, C's, L's, mosfet arrays in parallel&series combinations
with multiple banks etc..
A separate branch of electronics??

Anyways..
One new thing (I'm always a newbie) I noticed on
http://www.genomerics.org/patent/patent.html
was the 2 chained (L form) inductor/mosfet sections.
Or is it pi form.?
All reminds me of high order filter design with passive RLC.

I'm curious about repeated L form inductor/ mos sections..
Let's say this is extended to a 3, 4 or 5 sections... Would such a
circuit have benefits?
Addressable inductor?
Digitally controlled variable inductor?
Maybe some fancy timing has some benefits...
For example:
Inductor 1 charges by mos 1 ...then inductor 2 charges by mos 2...then
inductor 3 charges by mos 3...etc..

As it says those two inductors are actually a coupled inductor. The two are
wound on the same core. It's done in that particular circuit so that when
the mosfet is on it applies a reverse bias to the IGBT by transformer action
of the inductor. I suppose the closest guess would be to call it an
auto-transformer.

As to your other suggestions.... Well, without knowing where you might be
going?

What the heck. However, if you carry on like this you are likely to find it
hard working with other people. You are meant to start out inside the box
along with everyone else so you can attend meetings with management where
they talk about thinking outside of the box.

If you start outside the box and do your thinking there then no-one who is
inside the box will understand what you are talking about even though they
are being advised to think outside it. At that point life becomes
frustrating..... Stick with it though.
