Hi all,
Does anybody know the working freqquency of the TL494 on this circuit? My question is because the output current capability will depend on the transformer primary inductance and on the frequency. Limits imposed by the potentiometer seem too wide.

Dear Black_Bird.

A "little bird" told me 5 KHz !!  ;)

Experiments will tell us more !!

Cheers Grum.

Thank you Grum. My calculations, supposing AL of the core around 2000 nH/turns2 and a current of 2A ( 30W /15V)
, and also supposing the duty cycle of 45%, 15 turns at the primary led to a frequency of 5.68KHz. So your "little bird" confirms my calculations.

You are kidding, right? The people in this thread can't even settle on which output pin of the 494 to use, and it seems you can just start leaving components out all over the place, or substitute different ones, at will. Compare Groundloop's PCB specified components with what we have just seen in the last few posts.

Why not settle on one specific schematic before you start making PCBs or worrying about what frequency to use?  Once one schematic is "approved" and constructed, that can become a baseline from which variations can be tested to see if they help or hurt the desired performance.  But having three different people (at least) putting up substantially different schematics, each saying that they believe theirs is the right one to use... and then someone else comes along without an actual build, apparently, and tells you to leave parts out.... OK, fine. Have fun. You are making a mess that will have to be cleaned up later, but as long as it keeps you off the streets, it's fine with me.

Lets take it a step further, the bemf from L1 causes the pos side of C3 to go high pos this draws current on the other side to go high neg after the bemf is dissipated through L2, L2 has a bemf that will cause the pos side of C3 to go neg this releases the high neg from the cap and pulses the electrode.

Hey, it was just a question from somebody who wants to build the circuit. For you knowledge, I'm and electronic engineer with more than 35 years experience and, despite that, I am not raging over people who know less than me. Sometimes the best solutions come from people with less knowledge but more ingenuity.

Grum,
I think I understand why the potentiometer is giving that wide range for the frequency: it is to allow for different AL values of the core. See the table below
AL.       Inductance (15 turn). Frequency for 2A current and 45% duty cycle
2000.         450uH.                      5.68 KHz
1000.         225uH.                     12 KHz
800            180uH.                     15KHz
600.           135uH.                     20KHz
400.             90uH.                     30KHz
200.             45uH.                     60KHz

Cheers,
Black Bird

TL 494 can be sourced from any old SMPS. :D
----------------

Seniors, please decide on one circuit, before the whole hound of researchers here waste time in making wrong circuit.

Electronics guys like Black Bird may analyse the circuit and its working before newbies like us start the replication. It will be much better if someone can tell how it works in simple language. From where the excess energy comes from in the system.

Are there some elements in the circuit which might be exploiting energy from COUNTER SPACE. Although I am not sure what counter space is, yet if some experts explain to us, will be appreciated.

Dear Google and all.

Welcome !!  :)

I have re attached the schematic that dear Groundloop converted to a PCB for us, see below.

As to the transformer. This IS the Grey area (Gray, for our US readers  :) )
There could well be a number of different configurations involved. Private discussions regarding what might be happening there?? Bloch wall movement between the two halves ?? Who knows ?? We will need to experiment !!

I too have had a moment when things seemed to come together and that BIG question hangs on your shoulders. Publish ? What in the Hell would be the outcome ? Complete collapse of the economy ? Social unrest ? War ? All these thoughts run through the mind !!

Well, to Hell with it !! Let's have a concerted, World Wide, no borders, discrimination free, BASH at this one !!  Just over 12 months ago I joined this forum, not knowing anyone !! I now feel a part of a massive world family, with a common goal. You have ALL become my friends !!  :)

ONWARD !!

Cheers Grum.

Dear Grum,

Thanks very much. There are some countries in the world not dependent entirely on carbon based energy. Those countries are meeting their domestic demend of energy and selling surplus energy to the neighbours.

Economy in those parts of the world are not crashing. See, if at all, we can make a free energy device, it would be of moderate power output and large industrial and commercial power requirements shall be still met by the conventional hydroelectric or nuclear based electricity.

We may get some respite from our power bills but powering heating and cooling devices shall still need grid based power. These gadgets can fulfill the lighting requirements only, IMHO.

Dear Black Bird,

Thanks a lot. This forum really needs people who can lead the group on this thread, courtesy Mr Grum. Some seniors join hands and please become the project heads for this thread.

Dear TinselKoala and all.

I opened this thread with the schematic, that I thought, would be correct for this replication !! It was the one presented by x_name41. The hand written mods that appeared there were built into the PCB that dear Groundloop has produced.

For me, that will be the one that is used. I agree with your sentiments as regards how much a mess we could get into by following different routes !! The simplified king-Grumage schematic was just posted to show simplistically that the circuit is driven by a very fast switch, nothing more !!

Your electronics expertise is well known amongst the older members of this and many other forums. And I look forward to a continuation of your, and other electronics oriented peoples input.

Cheers Grum.

Yes Dr. Koala, Black Bird and other electronics experts, please take the lead. You can really make this thread a humming hive and I wish and pray Almighty for the success of this venture.

Read my posts.

Dear A.king21,

Can you please suggest some interesting reading material on electrostatic systems with COP more than 1. Will be helpful for dummies like me who have long forgotten the basics.

Much appreciated.

Dear Grum,

The frequency limits for the RT and CT components in the schematic (1K+10K potentiometer and 3.3nF cap) are 363KHz ( Pot at 0 ohms) and 33.06KHz ( pot at 10K). Using this information, and the table I just posted, I would say that the transformer core (with the gap) has an AL less than 400. As the dimension of the gap will influence the final AL of the core, you can always adjust the gap to fine tune particular core you have.

Cheers,

Black Bird
