Wikipedia has a pretty good entry for it:
Boost converter - Wikipedia

Now most boards that can boost can also buck (the old DNA20 and DNA30 we an exception, they could only boost). So really it's probably a more complicated topology:
Buck–boost converter - Wikipedia

I saw the title, and was thinking this might be my longest answer to a question yet. I didn't even think about posting a link. Thank goodness for Wikipedia.

When you depress the fire button a small stick inside the mod pokes the angry pixies. If you turn up your V/W higher then it pokes them harder. They get mad and flap more quickly. If you toggle the switch higher/lower a lot then the angry pixies buck and boost around inside the mod, hence the terms. Just be careful not to do it too much or you'll let the smoke out.

    The simplest way to understand it is a transformer, depending on how many wraps of wire are on each side it can convert low to high voltage or vice versa, with a corresponding change of current so it doesn't violate conservation of energy principles. Of course a transformer only works on AC signals and also there are simpler circuits, but they all essentially convert it to AC in some way and obey conservation of energy.

    Depends on how tightly one defines honest, but both parties have more than one would expect. Which party you think has more generally defines which you belong to.

    How tightly one defines honest? Interesting concept, when honesty becomes a fluid concept, we are finished.

    Neither party has enough honest people to be worth the powder to blow them up.

    dumb it down for me
    A fast switch generates little pulses that get pumped ahead through a diode (check valve) by the special property of inductors (e.g. a coil made of copper), the resulting pulses on the other end get stored in a capacitor (little battery) and are "flattened out" to a continuous signal by another capacitor (or set of caps). To really get into it can be complicated since it involves good understanding of the interaction between electricity and magnetism, that's essentially the mechanism that makes this work.

    As the title says, who can explain how boost technology in a regulated mod works? I have a hunch that it involves PWM (pulse width modulation), but I can't explain how that works either.

    Explain it to the dumb noob.

    I think Basically what is going on is you have a Switch that can Open/Close Very Fast.

    And as the Switch Opens/Closes, the input Volatge alternates from making a Magnetic Field in an Inductor to being in Series with part of the Inductor. It when the Voltage is in Series that the Increase of Voltage occurs.

    But Nothing is Free conservation of energy-wise. So to get more Volts, you need to give up something. And that something is Amps. So you are Basically Trading Amps to get Volts.

    I just kinda have a 5 Mile View of what is going on. So maybe someone with More Knowledge can explain it better.

    Thank you, almost get it.:lol:

    The system is currently set up in such a way that “truely honest” people are simply completely unelectable. If pushed far enough there aren’t even very many honest people in the world, period. One generally has to settle for less honest or more honest.

    You have a little thingie that pushes. If it can't push hard enough, there's another thingie that stores some of the push. Then the first little thingie pushes again and the second little thingie stores some more again. After a certain number of pushing and storing, there's enough push to move something as far along and as fast as it needs to be moved.

    If the stored up pushing is so much that the third thingie moves too far too fast, the second thingie doesn't ask for as big of a push the next time.
