PJK book addresses stepdown transformer

PJK book addresses stepdown transformer

In the PJK Don Smith book, a graphic is shown with a stepdown transformer.  It is shown here:

No capacitors are shown here either, and said to be optional for tuning.  I will attempt to shift to my calculated values for the caps and be attempting to find resonance with a diode or neon bulb also.  Notice the resistor, as it seems a requirement.  On p82, it states:

"This simplified circuit avoids the need for expensive capacitors and the constraints of their voltage ratings, and the need for electronic control of the output frequency. The wire length in the turns of coil "L2" still needs to be exactly four times the wire length of the turns in coil "L1", but there is only one component which needs to be introduced, and that is the resistor "R" placed across the primary winding of the step-down isolation transformer. This transformer is a laminated iron-core type (as is my MOT!), suitable for the low mains frequency, but the output from "L2" is at much higher frequency. It is possible to pull the frequency down to suit the step-down transformer by connecting the correct value of resistor "R" across the output transformer (or a coil and resistor, or a coil and a capacitor). The value of resistor needed can be predicted from the American Radio Relay League graph (shown as Fig.44 in Don's .pdf document which can be downloaded from the www.free-energy-info.com website).  The sixth edition of the Howard Sams book "Handbook of Electronics Tables andFormulas" (ISBN-10: 0672224690 or ISBN-13: 978-0672224690) has a table which goes down to 1 kHz and so does not need to be extended to reach the frequencies used here. The correct resistor value could also be found by experimentation. You will notice that an earthed dual spark gap has been placed across "L2" in order to make sure that the voltage levels always stay within the design range."

Regarding my MOT, it has a feature where the high voltage winding is terminated to the iron core and frame as a ground.  Given that the Center Taps on the air coil is ground, I have decided that is a bad feature and have disconnected the HV winding, letting it float.  I have hooked up the L1, L2 and MOT without any diodes.  I get some nice HV voltage into the HV MOT from L2 and can get a nice spark on a gapped connector, but without the R at least, I am not getting much voltage on the low voltage MOT winding.  You apparently will lose the higher frequency operation.

L2 Construction

L2 Construction


I have not been able to find some essential components to build my L2 by the method found in the PJK's Practical Guide to Free Energy Devices on Don Smith Resonant Energy Systems publication. I think it might be easier than what I have so far, but I may try it next time, as I still hunt for what else I need for those construction techniques.  I have everything I need for my alternative and have started it.  Here is a picture of the components:


My basic construction will be each coil half will be shaped around the white rings cut from a 3.5 PVC pipe.  Each half will have a ring on each side and fastened together on 4 5/16" fiberglass poles.  Each pole will be countersunk and held by a 2-56 screw and epoxied also.  In order for the coil to have a 1/4" spacing, a slot will be made in each pole, but staggered by 1/16".  In order to make those slots I put 4 poles in a wood holder with the stagger step at each block on the side.  I can now make 4 slots on each pole, which I have already marked on the whit poles.  I will use 2 blades together to get the required .08" slot for 12ga. wire.   I calculate the coil length to be about 5" but the total length will be 6", in case I need to move out to gain resonance.


Making some progress on the L2 construction.

Stumped on switching inductance diodes

I wish to build an SG with a step down transformer to control output vs a voltage divider as shwn in this sketched diagram from my original source material.  Notice it shows the use of 6 diodes, 2 switching inductance diodes, I have assumed, as Chris has spoken of in this thread these, and a diode bridge.


  Here is the schematic of the "Early Model" with the 8kv cap bank in the PJK Smith book.  :

Looking for any input from members.  But here is how I plan to proceed.  First I will assemble the L1-L2 circuit with switching diodes and cap and look at output in an obtuse fashion as I am estimating 4000v on the step-up at L2.  I will also let L2 receive a weak input and see if a diode be used to check for resonance.  I am planning a distant broadcast from L1 to energize L2 for that.  I do not have a signal generator and if I can slightly energize L2 with L1, I may not need one just yet.   I am not interested in determining if I get the 4000 volts, whether or not it is OU at this point.  I have no ideas on how I could determine the performance of such a high voltage.

If successful results are achieved, I will look at building my own stepdown aircore transformer built to operate at the resonant frequency of L2, hoping to stepdown the output to the 50-200v range.  A standard inverter can be used to convert to usable energy. in this range.

I have been thinking about a stepdown transformer coil that may have 2 layers of wire.  If you wind down one side of a tube on one layer and then reverse and wind back up in the same direction, THIS POTENTIALLY CREATES A PARTNERED OUTPUT COIL!  I am not sure that would be a good thing.  If things go as advertised, do we really need to shake loose anymore electrons at a potential 20,000 COP?  So goes the art of winding a transformer then...  Something to think about.  But I think, since it is a transmitter, would it be the 1/4 wavelength coil?  I would think not.  It must have more turns than the secondary.  I intend to study stepdown transformers now, but I would like to throw out a question to members on its construction.   I think that the secondary as a receiver of 26.8 MHz, needs to be one wavelength, about 36'.  Since I wish to run a ~50v inverter off the secondary, it needs to step down the voltage a factor of 80.  So the primary would need to have 80 times the number of turns of the secondary, but yet still be evenly divisible by one wavelength in order to resonate at the system's frequency.
