POC input circuit

Guys, I tried these configurations in order to produce the positive half of a sinewave trace:

For the first configuration I tried this resonant tank thanks to Vidura's advice:

I am able to produce a nearly sine wave with it, but it's not the desired positive half of a sinewave trace (sine wave half wave rectified). It's an entire sine wave.

Any idea how to obtain this?

Hey CD,

Good work!

Adding a second Coil, like a Transformer, with a Diode on the secondary, will half wave rectify the AC Signal:

Hope this helps some!

Hi, buddy,

yes, but this means there are 2 cores, the one above and another one for the POC setup?

Hey CD,

It means if you want to use only a half wave, then you need to accommodate for this. Yes, if you want to use the Half Wave, then a second core is a good way to do it.

You could use a SCR Cap Inductor discharge, but this is more work again. Time t = R x C

Sorry, I may have confused you at some stage. Using a half wave, suggested here, is a good way to learn the timing. But we must think 1/4 Wave timing. Breaking the waves into Quarter Wave parts:



This is exactly a timing problem.

If I may suggest CD, keep the information, keep this all fresh in your mind, because it is important, but move on to the new thread: Important: Delayed Conduction in Bucking Coils 

This thread incorporates all the last bit of information and goes a little deeper into the way this works. Giving you a better understanding of how the Waves interact together, using Delayed Conduction techniques, which are the same, but easier to work with. A much easier way to see how the timing works!

Timing is a critical aspect to these machines, we need to see the interactions between the Waves for their Value.

Hey, man

Thanks, but it's confusing. Do we need some time off on the input or it's not mandatory?

Hey CD,

Yes, the input Frequency and Duty Cycle is important, no matter what method of timing is used. Remember how Graham Gunderson said:


and here I delay that, so its not a perfect sine wave, and there is a reason for that...


Well, he did not give an answer. But, I know the answer, and I will tell you for free!

Look at the Output Current. If Graham did not delay the sine wave, then the "Generation" of Electrical Energy would be cut short. The Output would be greatly reduced! The Output may not reach gains above unity.

So, the Delay, is effectively a method of changing the frequency and duty cycle of the machine. Allowing for a longer Off Time of the Input.

Exactly, it needs time to "breathe", as you said. I guess I have all the pieces to try to replicate the MIT and I don't think I need  expensive MOSFETs. It can all be done cheaply.

My Friend you're much further along than you might think!

I read the other forums from time to time, all I see is fighting and bickering! A select few are picking others to bits. Shooting others down, for having an opinion. Weather the opinion is deemed to be correct due to ones perspective is another debate.

They lack direction!

Like I have said, we are truly Light Years Ahead of the other Forums!

We have Direction! We have Momentum! We have Knowledge!

Look back and see where we were yesterday, and now again today! We are moving forward! We have the technology, the only thing we have to work on is how people understand or perceive it.

Its actually not that hard to make work, its hard to understand what needs to occur to make it work wink

Be proud, we are already a part of History, we have already changed the world! Only 5 years ago, I was battling with Trolls, trying to introduce this technology, today this technology is main stream and we have Eliminated Trolls!

cd sharp - Check out "Little Fuse" (and others) SiC MOSFETS [Silicone Carbide - fast and robust]. A few dollars and they seem quite liberal with samples - pushing their tech; which is good all around...


Chris - How correct you are (tell me about it undecided )

Have a good one fellows!

The great Nikola Tesla:

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago go by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
