Are Tommey Reed´s pulse motor circuits overunity ?

[gyulasun]

Thank you @gyula !

Will you be so kind as to make the changes you want on the graphic in order for me to understand what you are explaining so technically.
I will gladly make the changes and learn something on the go.
Remember I have no electronics background.

Hi Jesus,

Yes, I have made a change: I deleted the 7805 and made a red dot to the power supply wire of the TC4429: it should be connected to the 12V input battery positive pole directly.  I would not use a 7812 voltage regulator for feeding the TC4429 because the peak driving current requirements of the parallel MOSFETs can easily demand higher than 1 Amper peak currents a 7812 is unable to supply (it is limited above 1A or some versions of it above 1.5A).  If somebody wishes to use a 12V regulator for feeding the TC4429, he should consider a heftier regulator for the job.  To understand this better, here is link to a linear and switch mode voltage regulator handbook, see Figure 10-2B, pdf page 76: http://www.onsemi.com/pub_link/Collateral/HB206-D.PDF
Doing some calculation for the Gate-Source capacitor charge current for ,say, 50ns switching time and 12V V_GS, with the four input C_GS of 13nF, you can get I_G=13nF*(12V/50ns)=3.12A  this should come from a power supply that is able to provide this peak current, hence my suggestion for using directly the input 12V battery. 

Finally, I have to tell you that while this suggestion does improve the switching efficiency of this design by reducing the switching losses of the power MOSFETs to a certain degree,  I cannot support Tom's overunity claim with this circuit, due to the measurements difficulties involved with most pulsed circuits.  I have already written in this thread earlier that the real proof of overunity would be to use a DC-DC converter and loop back its output to replace the input battery after the start-up.

You act like this is my first idea, rethink you comment. I do have invention and patents. What gets me people like you have nothing to show but words.
Where is your patents?
I have one and another panding.
The rotary piston engine #6,860,251 and the ratchet engine patent pending.
Just because I'm not educated as you might be, does not give you the right to dog someone you don't know.

I don't want your respect, just rethink your comments.
I can trash talk too, but I'm better then that!
Tom.

You can have as many ideas and patents as you wish. I don't mind.
But I do mind when you claim overunity from a Boost converter circuit.
Please listen to others than yourself for once......please!!!

Thank you @gyula !

I will pay a visit to that link and see what I learn.

But I do mind when you claim overunity from a Boost converter circuit.
Please listen to others than yourself for once......please!!!

You seam pretty cocky men..
As far as i can  read you don`t put up any experiment..
I really like the guys like you who speak VERRY LOUD and never make ANYTHING..
As you are talking here you seam to put STAN MEYERS STEVEN MARK and everybody
in the same ship??
Make up something and disprouve what TOMMEY did and THEN YOU CAN BE
CREDIBLE....
I have been on other discussion site before and there is always A BIG HEAD to divert
the discussion.....
So,,thats your turn draw your gun!!!!!!

There is an eastern proverb which may apply here----
“All instruction is but a finger pointing to the moon; and those whose gaze is fixed upon the pointer will never see beyond.”

All the experience and education in the world is no cure for a lack of imagination, this is why inventors have always succeeded where everyone else has failed. If you really want Mr.Reed to listen to others then maybe he will listen to an engineer---- Tommy don't listen to a word of what the critics are saying.
