    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??

    One new thing (I'm always a newbie) I noticed on
    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

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

    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.

    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

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

    We're all going to be famous! Exciting stuff :)

    Maybe not. Please email or call me.
  6. 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
    is in my head.

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