Bedini SSG - self sustaining

[plengo]

I have EXCELLENT NEWS:

My next step was logically to try to scale this thing up. So I did. On the schematic below you can see I added a few more switches. The frequency now is about 1 mhz.

The sequence of switching goes like this:
SW12 and SW11 are ON. SW4, SW8 and SW9 are OFF. Then I turn ON SW3 and OFF and right after turn ON SW4 and OFF. I do that sequence for about 10 seconds or less, until cap reaches the voltage of both batteries added up (I know strange).

Then I momentarily dump the capacitor into battery B1, for that I turn OFF SW3 and SW4 and turn ON SW8 and SW9 for about 1 second. Voltage of the cap goes to the same voltage of B1 and than I turn OFF SW8 and SW9. Now I go back to to the beginning and I repeat the process to infinitum.

The cap WILL charge to the voltage of both batteries added up, and that is FREE. Strangely enough battery B2 will also charge while the process happens.

Important to understand the SW3 and SW4 are never ON together so there is NEVER a closed loop
except when dumping the cap into B1.

My next step will be using a series of batteries in series and see what happens. Since there is never a current flowing (except when dumping the cap into the battery) it will scale to very high voltages pretty well. The voltage increase is about 10th of a volt per 10 minutes in each battery. I would say pretty fast too.

Fausto,

Very nice setup with your switch. Maybe we need to use really high
voltage transistors to scale this up?

My new switch has not been tested yet on a "real" toroid coil. I will post
data and images on my new coil when it is done in a week or two. I'm
waiting (for the snail mail) for copper wire and a new toroid core.

Fausto,

Many thanks for running these experiments and for posting the results, which looks very intriguing to me.

May I suggest to look again at the possible energy getting in from the switching elements, by either: a) replacing batteries with some capacitors (initially discharged) and do voltage checks on all caps during switching and/or b) replacing batteries with variable resistors of relatively large values so in case C1 is charged by bleedings from optos/switching elements, by properly adjusting Rvars as to maintain VC1 approximately constant and by knowing on-off times, the small power input from optos (if it exists) could be properly estimated?

I apologize if the above were already suggested and/or conducted; my only excuse is that I didn’t have enough time to read the whole thread.

Many thanks again,
Tinu

@tinu

thanks for the comment. I have done the test using only caps instead of batteries for that exact point. No, caps will not work and the bleeding if any is meaningless to the point that voltage meters will only show the caps being discharged so that in less than 5 seconds the whole thing will simply stop.

It should be possible to measure any DC coupling between the
opto and the transistor. This would be so negative for the
opto component, I find it difficult to believe it would be designed
that way. You know, we don't want that DC bias and I'll bet
others don't either.

There are opto components that use photovoltaic cells in series
to produce some voltage from their leds. Field effect transistor
like to have their gates biased slightly above Vsource, and I guess
you could use this. As I have said there are all sorts of opto
component functionality.

Bets are off if you can find a magazine article describing use of a standard
opto-isolator this way.
