My Motors got me to Tap into Radiant Energy

You've got it right!

Hi Larry.
It is strange to see 30V requirement for the gate.
What kind of fets did You choose?!?
For most of mosfets the gate drive is 10V it even goes down to 5V for logic level fets and it usually goes a bit higher for IGBTs: up to 15V.
From the datasheet you will have to examine current/voltage curves for different gate voltages. You'll see that one 12 battery is good enough for driving this setup.
But let nothing stop you from applying those 36V to the coil
To get good and strong response from the ambient in the form of a BEMF it is required to go higher in voltage/current and shorter in pulse width. Ismael Aviso says that from his experience the pulse should be from 0,02 to 0,05 of a second.
Frequency of optimal operation depends on the coil. You can easily expect those oscillations go high in AC voltage. Times TEN! For My coil if I pulse it with 30V DC I get 300V AC!
What I do is I pulse the coil manually to do a quick test and watch the scope for response. The ringing of the coil in HF diminishes to zero after a certain period of time. This period is the minimum working frequency.

So my advice, if there is a scope nearby, is to check the coil and start slowly, just like Ufopolitics said, but to start from this calculated frequency minimum and go up from there.
This way the risk of burnt fets is less. Where for instance at very low frequency your pulse width can be waaay to wide...

Any pulse generator retaining pulse width independently from frequency changes would be more helpful.

Cheers
Peter

P.S. My ultra fast 1200V IGBTs and 600V Schottky diodes for the ultra fast forward bridge arrive tomorrow!
Can't wait...

Hello,

Yes, exactly that, very short pulses on our side...wider Off Times, and the highest in V of our pulses...the more we all get out from Radiant...
Great news that you are getting those HV Components...now you would be able to see it yourself.

Good testing

This Guy Has The Idea Very Simple And Well Defined...

Unification Coil Energy Boost w/ Solar Assistance - YouTube

He uses a small 12V Batt, assisted with a small solar cell...pulsing a Coil with a very simple 555...and obtaining 30 V output...no mosfet's, just a very low signal directly from IC...
However He does mention the circuit could be enhanced to higher outputs by use of mosfet's...
Excellent demo, I thought it would be useful for those starting on this set up.

Hi All
Since the FETs I chose to use has +- 30V gate I have decided to rebuild my oscillator using L272 (dual 40V Op Amps). This will not require any step down voltage for the oscillator and the whole thing can run on 36V. As near as I can tell it will operate within UFO's parameters (time will tell) at least as I know them at this point. Parts ordered... I will post results of finished oscillator.
So you all understand, when I said I would back off this, I meant I would back off asking so many questions and posting not leaving the thread. This is too important to me to not pursue it to the end. So for better or worse you are stuck with me (a quieter me ).


Regards
Larry

Dynamometer

You talked of how to get a dynamometer. The good news is you do not need to build one by yourself. Some newer excercise bikes (ergometer) have all you need. You can get them as second hand models quite cheap from people who once were shure they can get a body like Schwartzenegger but now sell their equipment because of constant disappointment. These people are willing to sponsor our research.
Choose a model with display of WATT. More sophisticated devices transmit their data via wireless link directly to your PC for documentation and they produce nice graphs as well.
Just an idea!
