Ghazanfar_Ali,

I have started to build this circuit. Got the Ferrite coil and heat sink for the mosfets mounted already.
Next step is finding some mosfets and solder the circuit together.

One question for you, you say that if the load is low then the electrolytic capacitor will charge.
My question is, if I connect the circuit to a 12 volt lead acid battery, then will the battery charge
with no load on the circuit?

Groundloop.

As far as 800W output sim file is concerned, dont waste your time on that. It is unstable schematic. Damping occurred after 4 minutes in my case. However schematic of 42 W output is stable. I made it the hardware run for 1 and a half day and the bulb was continuously lighting.

Ali,

I had already switched to the 42W version (i.e. 150 Ohm load), but the oscillation only holds at 200V for about 20ms, then starts falling off. I've tried 150k Ohms for the R1 load and still the oscillation eventually falls off.

We need your working ORCAD files here Ali. ;)

 @Ghazanfar_Ali
I think you should try driving the signal generator into
the led of an opto-isolator, then using a 6VDC battery
to generate the pulses out from the opto-isolator. The reason
is that the output of the signal generator will have some
capacitance to the utility line determined by the generator
itself with potentially high hum voltages. You really have to
 isolate the signal generator lines from ground with a low pass
filter. This is why they often have a circuit link on back the instrument
to separate the chassis ground from the signal ground on high
 quality instruments. But opening that link will not necessarily solve
this problem.


If the pulse are shaped the same you would need to ask
your self why can’t the battery do what the signal generator
did?
 
You always should isolate a signal generator from ground
before using it’s output where isolation maybe critical.

No the 12 V Bty will not be charged if you connect it instead of C2. The minimum driving voltage for the device must not be less than 24 V as an initial charge in C2 whether 150 Ohms load is connected or not. I did not test this situation but my hypothesis says that i may not work in case of 12 V Bty. But u can try.

Ghazanfar_Ali,

Thanks for taking time to answer my question.

I have built the circuit now. Did test the circuit on a 12 volt battery and the battery did not charge.
I will try 24 volt also. But first I will build a 555 driver circuit for the mosfets.

I am thinking that if we increase the voltage, the wire resistance may be less significant in the real circuit ..as in the  simulation.

However i will try again as soon as I get 18 uf of hv caps

Also what he said:

seems to be very important, as this zener diode gives the LC circuit always a kick.

Hi Stefan and Ali,

There is no any Zener diode across the output side of a power MOSFET i.e. between its drain and source electrodes. 

However, there is a so-called body diode between the drain-source electrodes, always in reverse direction with respect to the drain-source needed polarities.  This body diode is unavoidably created in the manufacturing process, see Fig. 1 and Fig. 2 of this paper here:
http://www.ixysgreen.com/Documents/AppNotes/IXAN0061.pdf 

This means that if you have a 200V max drain-source voltage rated n-channel MOSFET, the body diode is reverse biased all the way up to 200V as long as the drain gets max 200V positive DC or peak AC with respect to the source electrode. The moment the drain voltage goes negative with respect to the source electrode, the body diode gets forward biased (if the voltage difference gets higher than 0.8-1V of course in the forward direction) so current can flow via the body diode, regardless of the control voltage between the source-gate electrodes.
Of course, if you exceed the max 200V drain-source voltage rating the manufacturer defined for a particular MOSFET type, then the device will gradually start conducting current between its drain-source path, either via the reverse biased body diode or via the drain-source electrodes, bringing the MOSFET gradually or suddenly into a destruction process.

Gyula

PS:  Quote from the link: "The body diode is convenient in circuits that require a path for the reverse drain current
(called “free wheeling current”) such as half-bridge and full-bridge converter circuits in motor control applications".

PS2:  You can "neutralize" the body diode by using an outside diode in series with the drain,  this diode's cathode is connected to the drain electrode and the diode's anode will be the "new" drain electrode,  (use a fast recovery diode with correct reverse voltage and forward current ratings).  Of course this extra diode (if needed at all) increases the MOSFET switch's power loss ( which is the forward bias voltage drop times the forward current).

Hi gyula,

Wouldn't you agree that every diode is technically a "zener" diode?

IOW, all diodes have a reverse breakdown voltage, but the difference with zeners is that they are engineered to have a specific (usually a relatively lower) breakdown voltage. And we normally include a series resistance with them to ensure they don't burn up.

I've seen MOSFET symbols with a zener rather than standard diode pictured.

Some MOSFETs are "avalanche rated" meaning they can tolerate a certain degree of avalanching in the body diode (the IRFPG50 is an example).

Hi Point.99

I'm reasonably certain that this is ENTIRELY INCORRECT.  A zener is designed to switch quickly.  Not all diodes are capable of those speeds.

IOW, all diodes have a reverse breakdown voltage, but the difference with zeners is that they are engineered to have a specific (usually a relatively lower) breakdown voltage. And we normally include a series resistance with them to ensure they don't burn up.
Still not right.  Zener's are as brittle as any diodes.  Their rated voltage tolerance explains the limit of their capabilities.  And each one varies - zener or otherwise.

I've seen MOSFET symbols with a zener rather than standard diode pictured.
Then likely the zener in the body diode is designed to accommodate high switching speeds.

Some MOSFETs are "avalanche rated" meaning they can tolerate a certain degree of avalanching in the body diode (the IRFPG50 is an example).
No.  No MOSFET - least of all an IRFPG50 is DESIGNED TO ACCOMMODATE A DEGREE OF AVALANCHING.  Golly.  Whatever next?  Avalanching is the undesirable product of paralleled transistors.  And that applies to them all. 

Poynty - I wonder if these good people realise your rather unusual methods of power analysis.  It's not entirely topical but it would have some considerable bearing on any evaluations that you apply to their tests.  You really need to make this public - certainly if you're assuming the authority to comment on these experiments. 

Kindest regards,
Rosemary

gee im so glad this thread is about a self runner ...able or not we will see

It astounds me that any body with common sence could claim anything worthwhile without self run being obvious.

Calculation and measurement are fine ....after the FACT

Hi Mannix. 

I'm not sure that over unity and perpetual motion are actually the same thing.  If we're to believe the standard model then the most efficiency that any of us could expect in electric applications would be COP<1 or - at best COP 1.  Not even nuclear energy is expected to 'self run'.  And I do think we're somehow confined to the laws of physics.  The only question is does the electromagnetic interaction comply to the 2nd Law of Thermodynamics?  And the evidence is that this may need to be 'rethought'.  Not that anyone on these forums can seriously propose anything - myself included.  But what it does do is allow more and more evidence to be evaluated by our academic experts.  That's always a good thing.  And the evidence is MOUNTING that - indeed - we need to rethink our electromagnetic interaction.

Much needed - all this work that you guys do.  And I think that time will prove it all INVALUABLE.

Regards,
Rosemary

Long time ago I posted circuit which worked exceptionally well for driving car ignition coil. I had and still have no way to measure what is going on here but the solution was very simple indeed. Simple avalanche rated mosfet with extremally fast surge protection transil diode 1.5KE400CA bi-directional across D-S plus a varistor. Of course no 555 circuit ! Only fast fall-rise square wave generator on CMOS nand gates.

Forest,
I suggest that you use multisim like we are in this thread and see if it self runs. You could share it .
1 thing is for sure . Just because the sim runs does not mean the your circuit will run, but it is a good starting point as this particular circuit seem to make good use of the accumulated energy in the cap.

I made it with different values to suit wah was at hand and the sim ran fine ..the circuit did not

The changes i make to the circuit do reflect in the sim very well ..just not self running as of yet .

I hope there are a few "committed to accuracy" replicators out there as Ali does seem very genuine about it working in practice

I am making  the values in my circuit exacty as Ali's sim now with minimun resistance in the torroid and 9  2uf  250v caps . It sould be done in afew days or so

If it works rose might  write the theory of "self running gizmos made by inspired neanderthals".
