So, I'm a programmer getting into electronics and micro controllers. I'm studying everything myself, with nobody to ask or tutor me in any real availability. I've developed images of how different circuits and components work in my head, but in this particular situation I'd like to verify the validity of my ideas as to how a boost converter works.
In a very basic boost converter, you have an inductor, diode, capacitor, switch of some sort (transistor), voltage source, and some sort of load ala Fig 1 here: http://en.wikipedia.org/wiki/Boo... . I know it works as I've simulated and built a working model, but as for how it works I'm worried I may be making incorrect assumptions.
I have read:
1. Inductors gain higher current charges with higher voltages.
2. Capacitors gain higher voltages with higher currents.
I'm also to understand that:
3. Inductors, once "fully" charged (drawing 0V or close to 0V while maintaining a current) will let out voltage when a load is placed on them/the supply is cut. In the case of a fully charged inductor, suddenly putting a load on it will cause a sudden release of a voltage much higher than the source originally used to feed the inductor.
So, in the case of a boost converter, we charge up the inductor a whole bunch while the "switch" is on. Then when we turn the switch off, the inductor pops up this incredible voltage and current which gets sucked up by the capacitor as it reacts to the change. Is it the higher voltage being shown to the capacitor from the sudden release from the inductor that makes it charge to more than the voltage source (see 3 above), or the current bursting out of the inductor pushing up the voltage in the capacitor (see 2 above) that is giving us this boost in voltage? Or, since current is simply a factor of voltage when employing Ohms law with impedance/resistance, are both factors actually just part of the same thing?
Sorry if I've expressed my question poorly, I'm still working through all this so it's difficult to even know how to ask something like this. If nobody understands I'll try and reword it (and make it shorter?).
