OK, I am banging on but...... for those who might be interested.

Second page.... now sort of finished.

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?
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.

Why don't you send this into EDN or one of the Semi manufactures (of
mosfets) as an App note. I'm sure some one will take it for a few .

Cheers

Ooooooooooh, I might have to polish it a bit to do the EDN thing.
Manufacturers seem singularly uninterested..... it's just like Don Lancaster
says it is with the added disadvantage of me messing things up in the first
place.

Never mind..... you saw it here first on SED.

We're all going to be famous! Exciting stuff

That doesnt matter, Most publishers have ghost writers. They'll take your
idea and present it professionally.

I did...... either you are busy or my mail did not make it past your spam

I know, why don't you e-mail me.

OK, I won't jump immediately because I'm such an insecure wimp but the germ

Thanks

Busy. Wrote that one last night, worked 14 hours today,
replied just a few minutes ago as soon as I got home.
