Dear Ed morbus.

Thanks' that is a hand drawn representation of Akula's toroid device !!

See attached screenshot.

Cheers Grum.

Dear d3x0r.

With regard to the above video I have attached the schematic.

I have just come back from the lab after looking into this one "yet again" !! Now this scheme may look simple enough but that little box in the lower LH corner is in fact another switch !! It cannot be substituted with a Diode I have just failed with that !! I am able to raise voltage on output storage cap to 300 V within a few seconds with the diode removed but as soon as you reconnect the diode nothing happens.

I was using a 12 V LAB and a simple relay switch with change over contacts.  Driving into a 35 / 35 V  to 240 V transformer. L1 was my 240 V leg and L2 / L3 the 35 V legs. What is unknown is the timing. Could it be 1. 2. 3. in 360 deg's  ??

Perhaps someone could Sim this ?? I do know that L1 is 100 turns and L2&3 are 50 turns.

Cheers Grum.

The schematic has coils all together; but they say in the description that some are anit-phase...
where did you find the relation for the coils? although it makes sense somewhat that L2+L3 = L1

Okay I built a sim using LTSpice; (Falstad doesn't have the right kind of coupled inductors). 


there is a couple signal generators... the top left is to 'initially charge the capacitor'  It is long enough to make sure there is a full charge, then the first pulse is after the power source is removed.


I used switches where possible, because they are more like digital components; mosfets have a potential slow rise/fall...


the -plot is the first cycle after having charged the capacitor.


The timing looks like you should open S1, allow current to flow to a maximum in L1, and then close S1/open S2.... if you wait too long, the energy in the capacitor is completely drained, and the maximum momentum is lost.   So it depends on your inductances/resistances.


Vn001 is the voltage in the capacitor C1
Vn005 is the voltage on the 'inside' of L2/L3 (the side not near ground)
  (this is drained through the switch, to ground when the S2 is closed)


I(L1) is the current through L1....


The issue I have with this simulation is the rising current I(L1) should produce a current in L2/L3... but; there is a voltage potential (Vn005) which is against this induction;so the simulation says no induction takes place.


1) a ferrite core will produce more feedback voltage... (inductors)http://collections.infocollections.org/ukedu/en/d/Jgtz041e/8.3.html  an air core doesn't have that spring back, and just goes back to 0... but a ferrite core will bounce all the way to the negative voltage the same as the positive; this is not represented. (can't really find external information which confirms this)


Adding a core does more than just increase inductance; it modifies the behavior of the coil.


So other than for purposes of projecting theoretical timing the sim does not demonstrate correctly the circuit.
Added other components to help it resemble reality; series resistances added to coils, some capacitance added..

@Grumage


I had the schematic implemented wrong... I had L2 and L3 joined at the power circuit end.
I had another mistake but I don't remember what it was...
I changed the S1 mosfet with a switch; and adjusted threshold voltages so S1 turn on time = S2 turn off time and vice versa


the outputs of a the signal inverter should be used in both directions so the same time skew is applied to S1 times and S2 times.


For my sim I have L1=75uH L2=34uH L3=34uH,
time for S1 close to S1 open is 30us
time for S1 open to S1 close is 25us.
Edit (Added)
For my sim I have L1=8mH L2=2mH L3=2mH,  (L2/L3 are 1/2 the turns, which is 1/4 inductance
)time for S1 close to S1 open is 702us
time for S1 open to S1 close is 400us.   909Hz (1.1ms/cycle)?
(having updated the coils; the lag time between power producing pulses causes the load capacitor to mostly drain; but the inital pulse is higher than the original voltage, so a voltage comparitor could be added to feed the power cap (C1))


it's not a 50% duty cycle thing...

I have a better understanding; For the most part the first parts of description were right


1a) S1 closes; currents start to flow through all 3 coils; L2 and L3 will have opposite currents, and should cancel each other before hitting the core, leaving L1 to use the core for its inductance
1b) S2 open; from 0, there is no effect


2A) S1 opens; this is the power event, the resisdual momentum in the coils will pull a charge on the capacitor.  as the current stops in L1, a current is induced in L2 and L3 that reverses their current
2B) S2 closes; this forms a closed DC loop for coils L2 and L3 that now have their current in the same direction.  This loop diminishes with the resistance of S2 and L2/L3.


3A) S1 closes; (no difference from 1A); go to 1A; other than the momentums in all coils are now (possibly) already flowing in the direction which they will be when S1 is closed. (a difference from state 0 to state 1).
3B) S2 opens; the DC loop which is primarily formed from L2 and S2 is now open, and the current in L2 diminishes, inducing currents in L1 and L3 that are in the same direction as (1A).  Also because of the voltage buildup, the current in L2 will itself reverse; which will be an increasing current in the opposite direction ( which induces the same direction current as a falling current in the original direction).

I said (possibly) because if T2 is long; they will be at 0 current.

I see no advantage leaving S2 closed for a long time...(other than instantaneous). Actually...


for a time(T2) after S1 is opened, the load capacitor has a charging current flow, so S2(closed) and S1(open) should be long enough to take full advantage of the charging current.... but as that current is diminished, there will have to be more current pulled from C1(power cap) to get the same saturation point...


T2 Optimal would be above... if T2 is longer, power events are held off longer, letting more load capacitance drain through its resistance... so it should not be too long;
The load capacitor will charge higher faster with a shorter T2 than 'optimal' described above...


so; T1 long enough for saturation, T2 short enough to not waste momentum, and long enough to capture some momentum into the load.




this works as long as there is enough source power in C1....
with lower voltage in C1, longer time to charge to saturation...
Simulator using a pulse to charge C1 only allows 3 or 4 cycles before it's drained... and after the first cycle...
actually; increasing C1 to 1000uF (1mF) it smooths it out so I can have 1.5 seconds between charging C1
too low of a power will require T1 to be shortened.


Going to adjust inductances to be nearer to the large coils I have...

I have a 120-24V/12V transformer; primary measures 1.57H, secondaries measure 21.2mH
using these values in the simulator looks like it works pretty good too;
frequency 278Hz; 63% duty cycle
S2 closed 1.27mS (this shouldn't be much longer, can be slightly shorter)
S1 closed 2.0mS  ( this can be longer)


12V input voltage; Load capacitor charges to 33V, resistance over S1 closed time drops to almost 4V...
(only in simulator)
I don't know of a good solution for S2 in solid state; since the connections it's shorting are of arbitrary voltage normal NPN/MOSFET things cannot be used.
A wall transformer seems to have a high enough inductance that a relay might work; but relays are pretty high power things... I see that many optocoupler/optoisolators are actually transistor based...

Dear d3x0r.

I write this reply with a broad smile upon my face !! You remind me so much of my dear departed Mother !! All the technical stuff, but no mention, does it work ??   

Please do not be offended I find your application to these tasks as being quite rigorous !!

A possible answer and very low tech could be the use of a 3 pole Tesla switch. Having deciphered some of the text S1 and S2 are most definitely a flip flop ( Inverter/ed black spot ) box driving S1.
I feel that with larger inductances a slower switching rate could be employed ??

Your thoughts ??

Cheers Grum.

 

yes; but in applying this, I see some hope of it working


they are definately a flip-flop; one should open the instant the other closes.... thinking about getting a 12V motor and putting a wheel on it with strips of aluminum tape staggered so 2 leads short on one, as it turns, the other 2 leads short on the other... something like... forget whose it was (It was a generator with an armature that swapped between coils and capacitors)


Yes larger inductances definately reduce the switching rate (although increased resistance also); and increase the charging potential on the load.


I do want to put this together; was thinking I have some reed switchs too; could put magnets on the motor/wheel... a pulse motor with a stout flywheel doesn't require much power

Dear d3x0r.

Music, sweet music !!

Think about it for a moment ?? BIG 3 limb transformer like Stephanov !! Less resistance with bigger conductors !! This could be the start of something really great !! 

For the Tesla switch you could use pieces of Copper water pipe  slipped onto an insulating shaft and by cutting them with a triangular section create a variable "On" time. I could draw a sketch if you require ??

A.king21 and I are with this, and you 110 %  !! We thank you for doing the simulation !! 

Cheers Grum.
