Now that you can charge the cap real fast think at my mk8 i can charge 16 caps real fast 35 volts in 3 seconds easy , it may not fun something a rated at 35 volts dc , but even if it runs something at 5 to 10 volts that would be great.
My 3 seconds to 35v is on a 470uf 200v electro cap and it keeps charging but times 16 so 560 volt at 470uf in 3 sec , that is interesting power there.

In my Opinion you proved my charging claims and concept, Thanks again.

Edit @Xee2 @jardaro

Maybe a relay could do ? A STDT may be able to pulse 2 coils , cross induction would not be a problem i think and may even be beneficial.!!

HMM
I am really too tired to continue tonight.

I now see that A and C are from opposite sides of the split jt. I need to see if this is how I divided it. I think I separated it with the highest voltage. The wave is beau-ti- ful. At 60KHz it isn't a pure sine but it is all gentle curves that are almost half above the x and half below the x. I will try to send a pic, but  maybe tomorrow.

Doesn't the fact that a switched on transistor pose a path of less resistance to ground, wouldn't the transistor being 'on' cause less energy to flow through the path to the base based purely upon fundamentals of the electricity wanting to take the path of least resistance?

in a perfect world, yes.
in practice, it is not completely true.
an ignorable current is still present, but is not enough to trigger the transistor.

In some situation, a large inductance may behave like a non ohmic resistor with a time derived resistance - like a bell curve of sorts?

yes
while the currents is changing there are no resistance because induction only occure while the mag field change.
if the mag field stop changing, you will have normal resistance to the current flow.

I guess one way to test the idea would be to completely remove the ability for the inductive forces impeding current flow in the base coil from that of the collector coil..and simply have them not interact.  For instance by completely removing the coil to the base, and see what happens when they share a source voltage and current...  which I'm off to do right now.

that would be interresting.
the worst thing that could happen is killing the oscilation.

@ jadaro2600

Equivalent JT circuit. Transistor works as switch. Base coil is just to turn transistor on and off. Try it.

LOL, yeah, I see what's going on... I edited my previous post, after I set everything up, I realize that this is exactly as you have it pictured.

As always, thankyou xee2 for your patience.

@all, what is everyone using to create their circuit diagrams, ..DIA is giving me some minor issues with template images, I only have access to these inductors loopy inductors, I have to scrounge to create a transformer...  It takes some time.

I added really a lot of contrast so you can see the curve.

This is 2 combined wires. The frequency of something I think the coil is 60kHz and the voltage is around 85volts

The other pair is similar.

I think there is a lot of good potential here.

good night,
