Actually I do see it now without calculations.  =]

I used the same circuit and did a cutoff of 500v from 1000v source.

The receiver got 856v!   Now, we know that if we split 1000v 10uf into 2 10uf caps, we have 500v in each,  we know we are good with the power transfer. So the 856v shows gain with the source cap still at 500v.  We are good.  lol  It takes me time for some things to sink in.  I can say that I believe. ;]

And really before I was seeing it this way, but somebody comes along and says it dont add up, and then Im not sure about anything for a bit.

This circuit is an oddity though, in that if we want to use the output into a load, we need to dump the whole load from the receiver into a load in order to empty the cap to prepare for the next cycle.

Im sure that something can be done with it.

I think Nulpoints said to us a pulse or ramp charge. Im not sure if we could use a joule theif to bring back our source potential.
Well, Im tired.  More tomorrow.

This 100ohm resistor I put there after checking without it 
It was for purpose of draining oscillations so I could see when it stops but there is no easy stop  Resistor here is no following ohm law.
Maybe it's simulation error but it present very long oscillation afer disconnecting from power source

Hey Forest

It could be possible that the sim falters at times.  But when it does its noticeable. Like it locks up, or if you have diodes left 1 legged to the circuit. Like it doesnt know how to calculate that.

When ever you see an issue, always try to rebuild the circuit from scratch. I have exported problem circuits anf the problem was exported also.

I know this sim has some issues. But as I use it and know what causes the issues, Ive had less of them.

Like if you are deleting parts to change them, it is best to stop the circuit and not have it running during the changes. Thats when I get some issues.

Im going to try spice here soon.

Hey  Rose has some high value resistors in her circuit and has oscillations that seem to survive for a long period.

Im not sure what the extra inductor and switches are for in your circuit. Can you describe?  =]

thanks Forest,  I dont mind changes at all. Thats how you find things.

The extra inductor is here because for 220mH inductor it's hard to get the effect observable in simulation. Also it is due to low inductance aka Tesla stout copper bar.
I've lost exported data but circuit is easy modification of yours. Just charge source capacitor and dump into output cap to obtain more then 500V in output caps. This need also carefully adjusted simulation speed. When you got red color blinking between cap and inductor then it is in self-oscillation mode and output cap is not discharged at all or just barely. Voltage across inductor can be as high as 4 volts.
The other way would be to charge cutoff source capacitor aroud 600V and then connect both source and output cap in series and dump to source battery.

I see. 

Well I think we are there Forest. I think that now is a good time for experiments beyond what I have presented. So we can uncover more possibilities.

Keep them coming forest. negative results also should be included for the experience of it.

Be back later. By brother is coming over today. Its been a year.
