ENERGY AMPLIFICATION

I like Tito very much and miss his funny face 
I feel full of ambient energy , need a small reactor to catch it, but every mosfets like to blow from current peak, even self made igbt

here is the question : is there a difference when capacitor is charged from current source or from inductive collapse of coil ?!!!!!

A capacitor functions by storing and releasing electric charge.
This charge can come from any source.

If anyone thinks there is a difference when a cap is charged from a "current source" or from an inductive collapse.... I will suggest that they look at two identical capacitors, one charged to a certain voltage with a "current source" like a battery or power supply, and another charged to that same voltage by an inductive collapse.  What differences do you expect? How can you tell which one was charged by what method?

In a resonant condition, or a classical RLC ringdown, the capacitor is charging at one polarity, then discharging, then recharging _at the opposite polarity_ to a slightly lower voltage, then discharging, then recharging to the original polarity with a little voltage loss.... and so on until all the voltage is "lost" as power is dissipated by RF radiation and as heat in the circuit's resistances. If something replaces this little power that's "lost" in every oscillation, then the resonance can continue at constant or even increasing voltage, as the cap charges, discharges, switches polarity, and continues on.

The cap neither knows nor cares where its charge is coming from.... but it does care about frequency, pulse risetime, and voltage. These parameters will vary, between a DC "current source" and an AC inductive collapse waveform.

Thank you ,but I saw differences in discharge of capacitor charged with radiant energy and with current and with static charge. A lot of different effects.  A capacitor charged from radiant energy gives blue or green blast, with static charge like white or blue and both seems not affect metal used to discharge path. In opposite side : capacitor charged with current gives a blast with a lit of sparks comming and a damage to contacts.
I wish only that collapsing spike from coil will give me radiant like discharge from charged capacitor. Main point is my conviction that such bals could be passed via mosfets while ordinary huge current will definately blow them.

Well ....if you interesting about details, there is simple difference betwen charging capacitor from induction discharge and from hard battery source.

From coil, it is very short impulse which quickly fall, when voltage on capacitor is rising, so there is point where voltage on capacitor is letsay 10v when voltage from coil is on that time on 20v when the spike begins at letsay 60v, so the power which moves charges is at that time just 10v when on beginning was difference 60v applied on capacitor, thus this fall is falling also effeciency of charging.
From Hard battery there is no fall on voltage, so its actually little better.
To reach best effectivity on charging capacitor form inductive spike, you must chose value of capacity just right to absorb most of the energy from spike, when too big...then the spike falls even quicker, when too small ..it will just charge capacitor to maximum voltage and when it is done, rest energy in coil will by just radiated and lost.
Mainly it seems to me, in inductive case, best is to charge capacitor on desired value just with one single pulse, or at least smalest possible nubers of pulses, any next puls applied to capacitor which is already charged to some value will transfer just part of energy when rest is radiated.after charging it from single puls it is needed to transfer it somwhere els to secure empy capacitor redy for next puls.

I am little wondering about what you writte about difference betwen discharging capacitor from different charging source, in past I was trying several experiments but I never see any difference in later discharge. After using different way of charging, in experiments you talking about, are you using same capacitor in all three cases?same value of capacity.

I am also little curious about your wondering about amount of current when discharging capacitor in series with battery, tension force from the capacitor simply pulling another current from battery until the capacitor is neutralised. It is like connectiong two batteries in way they are in direct short ciruit. So they will explode if you do that. (or if you will use sufficiently large capacitor)
