This circuit should be the easiest to tune as well (Reason: when the pulse is at 6V, all transistors should be open switch, so logically, there will never be battery shorts). The pulse voltage source V5 can be replaced by a 555 astable circuit. V6 can be obtained by using an equal voltage divider (two 5K resisters, for example) sharing the same power as the 555 circuit. All the JBT transistors can be replaced with equiv. MOSFETs. I used voltage dependent current source and a resistor to mimick the behavior of a transformer. You can use 4 transformers instead in your implementation (MOSFETs are probably better than JBTs, I am affraid, as MOSFETs have no gate current). I used no diodes for switching purpose in this circuit. LTspice simulation is performed and the plot of the current over the load R3 is given below (I omitted the two capacitors at each end of the load R3 for the sake of simulation, in your implementation, you should include them).

I guess the circuit needs to be actually built to see if it works, theory is conclusive but SPICE seems to be still buggy when it has to deal with transformers/Inductances. Not sure if the suggested replacement components really translate that well into the real world. I can only encourage you to build it, the Tesla switch field is very promising.
What is the function of the 4 transformers in your circuit?
Voltage transformation for the transistors?
Or radiant spike creation?Last edited by Xenomorph; 02-10-2009, 08:01 PM. -
Thanks for the encouragement. I did not use transformers directly, but rather use something equivalent in the simulation. The transformers are Voltage transformation for the transistors. I will post a complete circuit with MOSFET and 555 timer later when I got some extra time.

the MOSFET version
Here is the MOSFET version, which is recommended.

Good looking, can you show the analysis graphs at R3 too?Comment

Sure thing
Sure, I am giving a detailed plot below. I am also using L1 to mimick the current effect when a transformer is used. To keep the reference voltage (Vref) effective and save energy, capacitors are employed.
How clean is the pulse on the load!Originally posted by Xenomorph View Post

To better understand the plan, please also see the drawing below.

If you want to have very clean switching, MOSFETs are recommended. If you use BJT transistors, there shall be current in the trigger coil, and it will take some time to shut off. With MOSFETs, NO current will be present in the trigger coils (which also implies that you can wind trigger coils with very thin wires), and therefore you can have very clean switching. Hope this helps.

You surly did build this Switch, because you describe it, as if you did.
Or is it just Hot Air, what you are blowing here out.
Can you post the results of the Circuit?Theorizer are like High Voltage. A lot hot Air with no Power behind but they are the dead of applied Work and Ideas.Comment

how I came about this plan
Here is how I came about this circuit:
First of all, the discussion on this forum here already pointed me to some very good information sources (well, some of them I knew earlier from other sources). The transformer idea is borrowed from the Eike Muller report, obviously
. But in that report, BJT transistors are used, which will reduce the chance of success since clean switching will be hard (if not impossible) to achieve (Well, the solid state replication was done by Panacea that follows Eike Muller report was not successful, probably for the reason I have given). Also, way too many diodes are used. I would like to get thing as simple as possible.
After much research and learning, and a lot of failures (in doing simulations), I came about this nice and clean idea, which is elegantly simple, but meeting all the design challenges without any compromise.
Now I put this into the public domain for those who are interested, and for those who can understand the simplicity and the beauty in this design.
But, I would rather keep the answer to your question a secrete: sorry, I just can't tell you -- it is really hard too
.
But I agree with Xenomorph, theory can't substitute experiment.

Joit, disregard my previous post about keeping a secrete. Since this is science, so let me be straight forward.
My comments are out of common sense, not because I have built one. When capacitors are used, I would recommend careful choice of MOSFETs too.
Hope you find this plan interesting.

Just dont expect, that someone will rebuild it.
The Internet is full with thousands of Plans and Theories from Things, and Peoples, what cite the Big Masters said, and deliver 'This Sure Works'.
But there is No Progress, its all only Hot dry Air.
They only bloating Sites, where nothing comes around.
When you have a good Improvement for the Switch, then build one, and put it into the Thread.
So simple.
But not doing a lot Theory, and, as allready did happen,
Make the big Thread about something like "This is the Free Energydevice",
and someone else did rebuild it, and nothing Worked, because someone had a Theory.
All what you do with unproven Theories is to abuse The Free Energy Devices,
what do work, or even better then normal one, and the Peoples what are working on it,
because, when someone spend his Time and Money to effort it, and build it,
and nothing Works, they Blame the Whole Free Energy and all the right Theories about, that its Crap and are Lies.
And only, because someone had a Theory, what Sure work.
Its even so simple, to start tinkering. Just take some Things apart, and you will see, how much usefull Parts are in.
And its way better this Way, that you can come to a real Solution of a working Device.Theorizer are like High Voltage. A lot hot Air with no Power behind but they are the dead of applied Work and Ideas.Comment

Seems like this thread is becoming a platform for personalized projections of frustration.
I dont see WHERE the creator of this circuit has ever made "Free Energy" claims ??? Clear projection here.
He has not even claimed that it would work, he is merely sharing a conceptional idea still on simulation level and discussing it.
If someone actually rebuilds it, then this person takes the sole responsibility for a possible waste of his time or the comfort of a successful circuit.
I might go ahead rebuild it if i find the time, it might get me ideas that i wouldnt have had otherwise maybe, who knows.
All a matter of attitude.Comment

This Schematic of this Tesla Switch is at the Original Free Energy Device.
Maybe you do a better research, before you do claims.
This Theme about is no personal 'Frustration' as you like to call it.
Its a general Statement. Not my Fault, when you cant see it yet.
It are the same Claims as like have a FE Device, so simple.
A modifcation of a Switch, what never was testet,
Topic is 'Simplest Solid State Tesla Switch' and not even build by hisself.
That smells like first Class Scam.
Well build it, spend Time and Money and have Fun with it,when it dont work.
Maybe its something nice for your Wall.Theorizer are like High Voltage. A lot hot Air with no Power behind but they are the dead of applied Work and Ideas.Comment

project
lanenal,
With the tools you are using it should be possible to export the components from a model and generate a parts list to order from mouser or the like.
A detailed schematic, PCB routing instructions, and a web configurator with a buy now button can't be far behind.
Punch the button, put it together, then put up a live 24/7 video feed of it doing some thing useful forever.
You'd get my vote.
Peace
