Since my electronics knowledge fails, my considerations are based rather on my reasoning' thinking. So, tell me guys, if this is what you are seeking recently (though it's not ready solution, I consider it rather a kind of a view of the problem):

"Transformers as magnetic amplifiers
The so-called saturable reactor in which a control winding is impressed with d.c. in order to vary the inductance of an a.c. carrying winding can be considered a primitive magnetic amplifier. Except for the way in which it is used, the device resembles a transformer. Indeed, a conventional transformer can be operated in this fashion ~ the basic idea is to control core saturation so that the second winding changes its inductance, thereby controlling the a.c. in the load.
Usually, however, the term 'magnetic amplifier' is reserved for a very similar device which also exerts its control through core saturation. Known also as a magamp, this device does not rely upon the d.c. control winding to actually saturate the core, but only to govern the amplitude level (and therefore, the time) at which core saturation occurs during the cyclic excursions of the a.c. in the load winding. The onset of core saturation switches the inductance of the load winding from a relatively high to a very low value. Therefore, the duration of load current within a half-cycle is subject to control."

Hi Qwert

No this isnt really very close to what Ismael is doing with "coil shorting at peaks"....

look into the Thane bi-torroid transformer for some cool transformer performance, also look into Hector's TRANSVERTOR experiments and circuits - a guy named selfonlypath has 3 videos up about it -

the EXTRACTION of power from caps in the transvertor is similar to Ismaels extracion-circuit (two stage I call it) it has 2 caps that output to load (via "diode plug" circuit ) in see-saw fashion  (one cap fills while other cap hits load and vice versa - alsways with cap disconnected from "source" when a cap hits load)
filling up caps fast without reflection onto primary as additional power draw is one thing to accomplish, (shorting coils into caps at sinewave peaks does this) getting power from those caps into a load also without reflection back as additonal power-draw to primary draw is another ("two stage" output cirucit - have caps disconnected from source that already filled caps, when caps hit load)...

Hi Qwert...
So, is it like this? Description:
"A number of capacitors are charged in parallel to a given voltage, V, and then connected in series by spark gap switches, ideally producing a voltage of V multiplied by the number, n, of capacitors (or stages). Due to various practical constraints, the output voltage is somewhat less than n×V."

Or rather like this? Description:
"A full-wave CW multiplier
The CW is a voltage multiplier that converts AC or pulsing DC electrical power from a low voltage level to a higher DC voltage level. It is made up of a voltage multiplier ladder network of capacitors and diodes to generate high voltages. Unlike transformers, this method eliminates the requirement for the heavy core and the bulk of insulation/potting required. Using only capacitors and diodes, these voltage multipliers can step up relatively low voltages to extremely high values, while at the same time being far lighter and cheaper than transformers. The biggest advantage of such circuits is that the voltage across each stage of the cascade is equal to only twice the peak input voltage in a half wave rectifier. In a full wave rectifier it is three times the input voltage. It has the advantage of requiring relatively low cost components and being easy to insulate. One can also tap the output from any stage, like a multitapped transformer".

hi Qwert

yes those have similarities - Ismael I know uses a voltage-cascading circuit in his "repelling force" coil blaster tech that can knock a 1 kilo weight coil in air 33 feet in less than second and he can do this 16 times over and over with power supply being only small 9V battery with two AAs in sereis for 12V power supply...12 second charge time for the 7500VDC capacitor between blasts - the small batteries drops about 1.3V  from 12.7 to 11.4 after those 16 blasts...

anyways the repelling-force has a special voltage-cascading circuit in it....so he doesnt just ramp up the voltage with a transformer or invertor - there is probably much more to it too, as backemf recovery makes for lots more voltage in cap, and also single-short-at-peaks coil shorting does too (X20 expect in either)

also I know that in the discharge-event from caps filled by "ambient" as Ismael calls it, he has a battery in series to the capacitor during discharge-event of cap to load (this his MEG tech not his repeliing force tech) and this battery works like a buffer/filter to prevent very destructive EMP harmonics....so the "series-cap" paragraph you quote is also "similar" but not really the same thing...really the "heart" of his systems is the coil shoritng at peaks - first short at peak creates oscillations,
then the socillation-peaks get shorted at their peaks -
so coil-short-created HV and HF oscillations expand in voltage rather than decay...so it becomes exponenetial voltage increase you couuld say that fills caps up...
also interesting thing is the process of filling up caps REQUIRES zero voltage in caps or there are problems since caps will be "polarized" one way,  and caps wont accept "ambient" power if they have even a little bit of voltage in them -  this since the tesistance from being polarized kills the whole effect; similar to having resistance acorss caps,
or switching that has high resistance to it too will kill the effect (why must be high-amp mosfets) just learend about the zero volts needed in caps to accept ambient power last week from Ismael...

Hi, all.
My two citations in my previous post are excerpts from two Wikipedia articles: one is "Marx Generator"
http://en.wikipedia.org/wiki/Marx_generator

and anoiher one is "Cocroftâ€"Walton generator" (to get there is only one way, through above "Marx" link).
So you, Konehead confirm that this sounds like the Ismael Aviso's technology. Of course I understand that the Marx Generator / Cocroftâ€"Walton generator is only one, but basic component of Aviso's generator.
