@ All

Well I came across some magnet wire here at the ocean, on the last leg of my vacation and had to begin to wind.  (I have 6 pounds of 20 gauge on my porch of my farm, delivered by UPS, back home.) 

It took a bit to get the hang of winding.  Bob is right when he says that bee's wax is your friend!   ;D   I got the hang of it, and it went fairly quickly.  The other winding will be easier, now that I have the hang of it.  I probably over waxed it, but the windings aren't going anywhere!   ;)

It took me 1 hour 44 minutes for this one winding.  Wound the Magnetic bias longitudinal winding first.  Counter clockwise, starting from the top to the bottom.  48 turns.  Labeled the leads.  Tomorrow I will wrap the top.  From what Weri tells me, the inside core is the tough one.

@ Eldarion

A "proper" Bob Boyce coil is coming soon!  A "real" coil fitting of that controller!   ;D  Then we will see what sort of waveforms you generate!   ;)

Warm regards to all,
Bruce

3.  Collector is Magnetic Loop Antenna, made of lamp chord wire, wound flat.  Inside loop is antenna, outside loop is for output.  First collector is tuned via tuned tank, to the fundamental.  Second collector is tuned tank to the second harmonic (component).  Third collector is tuned tank to the third harmonic (component)  Frequency is determined by taking the circumference frequency, reducing the size by .88 inches.  Divide this frequency by 1000, and you have your second harmonic.  Divide this by 2 and you have your fundamental.  Multiply that by 3 and you have your third harmonic component.  Tune the collectors to each of these.  Input the fundamental and two modulation frequencies, made to create replicas of the fundamental, second harmonic and the third.

4.  The three frequency's circulating in the collectors, both in phase and inverted, begin to create hundreds of thousands of created frequency's, via intermodulation, that subtract to the fundamental and its harmonics.  This is called "Catalyst".

5.  The three AC PURE sine signals, travel through the amplification stage, Nonlinear, producing the second harmonic and third.  (distortion)

6.  These signals then travel the control coils, are rectified by a full wave bridge, and then sent into the output outer loop as all positive pulsed DC.  This then becomes the output and "collects" the current.

P.S.  The Kicks are harmonic distortion with passive intermodulation.  Can't see it without a spectrum analyzer, normally unless trained to see it on a scope.

Hi Eldarion, hi All,

The gate oscillations on the scope photo appear to me to be excessive.

The attached image shows the way to perfection, if you can't reach perfection,
then at least know what it is and try to come as close as possible.

The gate charging current does not come from the power supply; it comes only
from the by-pass capacitors on the FET driver.

I can not stress enough how important it is to keep total loop lengths as small
as possible.

Hi Earl,
I thought XR7 were high quality caps.

I have just order a delay line device for creating a programmable pulse width:
DS1023S-100+
http://datasheets.maxim-ic.com/en/ds/DS1023-DS1023S.pdf

10ns to about 250ns in 256 taps (1ns steps).
Whats more, it can also be used to offset the input pulse by the programmed delay time, so you could use it for fine phase adjustments.
These come in a nice and small SOIC package but they are expensive, about 9.50 GBP each, Digikey seem to sell them a lot cheaper than this, but for me to purchase from Digikey I need to order 100 GBP worth of parts to get the free postage.

Regards
Rob

Earl,

Just so you know, since the gate drive was not the "primary" signal I was measuring in the picture above, I used an old crummy makeshift probe on that signal.  The oscillations are far less when I use the correct probe to measure that signal!

I have extensively bypassed the gate driver chips with 0.1uF ceramic disks directly connected to the power supply pins (I mean zero lead length here ;))  This is in addition to the heavy electrolytic filtering I have on the power supply input.

However, if this is not adequate, I would welcome other suggestions! ;D

Hello All,

Just over two hours winding time last night, for the top longitudinal winding.  It was a bit tougher.  Sore thumb.. ;D

Edit:  I wound CCW, winding from the inside to outside, 26 turns on this one.
