High voltage impulse generation by series switched mosfets videos

[evostars]

I made 2 new videos, they show the series mosfets switching together, using a basic Radiant power circuit (2019 april),
This makes it possible to create high voltage (3500V) impulses, from coil discharges, using 2 1200V SiC mosfets in series switched.

This video explains the idea of mosfet switching, and the Tesla oscillator article is explained:

This new video of me, shows the series mosfets switching:

Multiple mosfets could be used, but the bottle neck would probably be the isolated gate driver (which could be a optocoupler with glass fiber)
, and the isolated dc dc converter (which could be a battery).
I tried using 1700V mosfets, but their pinout was wrong.
The c3m1200V mosfets are on order but should be available later this year.

Many think Tesla only used capacitor discharge current impulses, by making use of quenched sparkgaps,
.but he used coil discharges in his later years of research, to create voltage impulses

My idea still is to use a dual primary setup, one for dielectric induction (use the pancake coils as capacitor plates), the other for magnetic induction

one one link per comment apparently on this new forum layout.
here is the second video showing series mosfet switching

It works.
I made a half bridge circuit, from 2x2 series mosfets. This way the impulse voltage can be made much higher.
This way I have series resonant primary coil, that is impulsed on both its maximums, just like a Tesla oscillator that is fed with AC

Nikola published his oscillator circuit in the July 1919 edition of the Electrical Experimenter.

I have made a solid state version of this circuit, to explain, how to phase shift a resonant cycle,
to get the voltage impulses anywhere on the resonant cycle.

This is done by using magnetically repulsing coils. Also known as "bucking coils"

in short:
a pulsed L1 coil repulses a series resonant L2 coil, which receives the impulses from the pulsed L1 coil.
Due to the repulsion, L2 is pushed out of phase.
This phase shift is done by varying the coupling distance between the coils.

This way the VOLTAGE impulses (which are resonant half waves from the L1 coil) can be tuned
to the L2 resonant CURRENT maximum.
This way the voltage and current are combined, creating power.

This is the video link, which shows and explains the concept deeper:
