At this stage I am waiting for R M Cybernetics to get back with a price for the manufacture of the PCB's. I myself do not feel confident enough to build a working circuit. Perhaps if any members are interested in purchasing the boards direct from RMC, they could make it clear here. A run of 10 or more would certainly be cheaper than one or two !!

Cheers Grum.
Please post here or PM me the cost of each board with shipping.

Thanks

http://www.tuks.nl/pdf/Patents/Benitez/GB191417811A.pdf


In this 100 year old patent Benitez uses an electrostatic generator to energize one plate of a HV capacitor.
He then alternately pumps the ground via a Tesla controller/interrupter switch to energize the other plate of the capacitor.
He intercepts the ground surge with a 1:1 trafo.
He then diodes the output back into the input.
The device is self running.
We can do all this electronically.
It took me 2 weeks to understand the patent.
The patent was granted.
Those with working Tesla coils, Slayers, Karchers, etc should think of their devices as electrostatic generators
and modify their circuits accordingly.


Thanks for the post. I read the full patent, and not understand the commutator, its timing.
Could you please explain it or a clear picture etc etc.

Also i want to make a Benitez thread, can some one tell me how i can do it.
I can not find any link/facility to make any new thread.

Cheers.

Even I studied Benitez patent and drew the circuit to understand it. Everything is easy to understand except the commutator thing. It uses the  following parts only :

1 commutator
10 diodes (probably HV)
4 capacitors (probably HV)
6 trafos (probably aircore/ ferrite core)
1 load

Circuit is simple to make except the commutator thing that seems very complex in working and concept.

I also second starting a new thread on Carlos Benitez 1914 patent.

Found this interesting video on Benitez Plug.

For self running LED light circuit the transformer is crucial part. And unless someone will try to wind coils and test on 555 circuit with same secondary coil connections as in original circuit there's not much to discuss around it. The practical test would reveal much more with asynchronous windings and flyback effects mixed...

Understanding whats happening in this circuit is critical to making it work.
This is electron flow not the conventional view.
This is the coil reactions - separating pos and neg

DilJalaay / a.king21,

In the Benitez circuit diagram two connections are dotted lines. Namely between points 5 --- 51 and 27----53.

What is the significance of the dotted line. Can you please reply.

Thanks in advance.

Best,


There are three doted lines, the circuit attached to the doted line is optional, it is if you want to use low frequency, without spark gap. All is written in the patent.

Many thanks DJ, I didnt read the full patent, its on my to-do list, I wanted to see the circuit first. Speacially the commutator part. Looks will take time to read and understand the basics of the patent first. But this seems interesting to me.

Is anyone starting a new thread on Benitez patent of 1914 ?

Best,

Grumage

30/8/7 ---- 8/7
How did you get the windings from that picture?

Dear 4Tesla.

The schematic clearly states L1 having 15 turns and L2 45 turns.

From that, and the assumption made by T-1000 then a first layer of 30 turns with a following second layer to the centre of the bobbin of 8 turns and a final layer of 7 turns makes L2 45 turns total.
And then L1 wound over L2 to the centre with 8 turns and a return layer of 7 turns makes L1 15 turns.

I hope that clarifies your question ?? And is of help to others !!

Cheers Grum.

Hi all

what is this mean ?

I might be speaking out of turn because I haven't read the whole thread yet. I've skipped through it.  It is a very strange configuration. In answer to your question re the "plate" :- I think that this represents a shield winding. This is generally a grounded turn of foil wound between the primary and secondary windings. Its purpose is sometimes for safety reasons so that there is complete galvanic isolation from the primary(used in mains fed circuits where human life is at risk eg on medical machines). In this case it will serve to reduce capacitive coupling between primary and secondary. With this configuration its only real effect would be to reduce stress on the diode D5 by reducing high frequency reverse bias whilst the diode is still switching off (I am referring to component designations on the redrawn circuit because it is so much easier to see).

The circuit is essentially a flyback configuration with the primary is used as a choke, not a transformer.  It is a current controlled circuit with R17 as the current shunt in the feedback loop. TL494 pins 1,2 and 3 form the current loop. Pins 15, 16 and 3 form the voltage loop. The secondary seems to only provide an auxiliary feedback mechanism.

There are lots of funnies in this circuit.

--For example why use the 7812 regulator. The feed is 12 volt battery and depending on the particular flavour the 7812 has a dropout voltage of about 2.5 volts hence no regulation. All the devices fed with 12 volts can withstand up to 20v. the regulator doubly pointless.

-- The control loops are unusual for no apparent reason.

--The secondary(auxiliary) winding serves no real purpose and introduces further losses. It probably boosts the voltage into the primary but what for? The energy for this comes from the primary flyback voltage.

-- Why couple the secondary winding to the output of the primary?

Lots of questions.  I must say this has intrigued me and I'll look at it further when I get a chance - hopefully later this week, but my first reaction is that this is simply a poorly designed flyback boost circuit. Perhaps some of these comments will trigger other peoples' ideas.

Good Day Tseak:

I might be speaking out of turn because I haven't read the whole thread yet. I've skipped through it.  It is a very strange configuration. In answer to your question re the "plate" :- I think that this represents a shield winding. This is generally a grounded turn of foil wound between the primary and secondary windings.

With this configuration its only real effect would be to reduce stress on the diode D5 by reducing high frequency reverse bias whilst the diode is still switching off (I am referring to component designations on the redrawn circuit because it is so much easier to see).

Plate could be electrostatic part of ground loop : to maintain ground when battery is disconnected.

The circuit is essentially a flyback configuration with the primary is used as a choke, not a transformer.  It is a current controlled circuit with R17 as the current shunt in the feedback loop. TL494 pins 1,2 and 3 form the current loop. Pins 15, 16 and 3 form the voltage loop. The secondary seems to only provide an auxiliary feedback mechanism.

In theory  the feedback should track frequency?

There are lots of funnies in this circuit.

--For example why use the 7812 regulator. The feed is 12 volt battery and depending on the particular flavour the 7812 has a dropout voltage of about 2.5 volts hence no regulation. All the devices fed with 12 volts can withstand up to 20v. the regulator doubly pointless.

Yes, allegedly the circuit will put out over 35volts when battery is disconnected and is left to free run:  Must check specs on IRF3205  MOSFET Gate to Source volt max.; could be there to keep stable voltage for Max voltage limits. 
I agree a Buck/Boost converter would be more efficient if that is the reason.


-- The control loops are unusual for no apparent reason.

Don't understand them either, yet!!!

--The secondary(auxiliary) winding serves no real purpose and introduces further losses. It probably boosts the voltage into the primary but what for? The energy for this comes from the primary flyback voltage.

According the supposed operating principal:  the L2 winding is processing and injecting the flyback voltage from L1 during the OFF cycle of L1 to the In-put side of the Voltage Regulator to keep the thing running when the battery is disconnected.

-- Why couple the secondary winding to the output of the primary?

To recycle the flyback energy?

Lots of questions.  I must say this has intrigued me and I'll look at it further when I get a chance - hopefully later this week, but my first reaction is that this is simply a poorly designed flyback boost circuit. Perhaps some of these comments will trigger other peoples' ideas.

Yes, we need more people to analyze this circuit and build it:

Take care. Peace.

Can someone who is Russian speaking inform Akula about this thread in his  honour?
If he wants to contribute in Russian it is fine.
We respect him here.

I have invited him to join in here and over at OUR.
