Kapanadze Cousin - DALLY FREE ENERGY

[verpies]

@ all

After rewinding the primaries according to the circuit/diagram designed by verpies and publiced in post #120 the main generator is stable and produces clean square wave voltages.

Both primaries are 20 turns of this double speaker wire over the whole circumference of the yoke

The voltages on the both secondaries is much to high (almost 900V square wave), so i will have to lower that, but for the time being i could show you the several signals present on the several windings of the main coil and how the tuning of the frequency influences the resonance of the L2 coil.

Finally i pulsed the coax with HV pulses of a flyback to see what is happening on the L4 coil.

With a big thanks to verpies.   Now continuing with the building of the nano-pulser.

OK, now we have an efficient 5kHz and stable driving circuit that can take the energy returned to the secondary and return it back to the power supply.  Stronger and faster Shottky diodes (D3 & D4) still would be a good improvement to it.

The MOSFET gate drive still could be made stiffer and faster by adding two more small BJTs per gate and the whole circuit still suffers from small spikes which are due to non-single point grounding and non-single point Vcc distribution as well as inadequate bypassing of the TL494, and excessive wire lengths, but this should not matter much unless you are a perfectionist.

The coax pulsing with the TV Flyback transformer nicely demonstrates that the pulses are not entirely confined inside the coax.
The conventional theory predicts that for an ideal coax shorted at one end, the waveform applied to the other end of the coax will be reflected from the shorted end but the resulting electric and magnetic fields will be completely contained inside the coax.

Itsu's experiment shows, that in practice, the pulses applied to the real coax are somehow coupled to L4.
Maybe the coax leaks or maybe it interacts with L4 via evanescent waves or something else entirely.

If the ns pulse amplitude is high enough, the above phenomenon should also make it possible to sense these pulses traveling inside the coax by fast SR-Latches, without the aid of an expensive GHz oscilloscope - all from the outside of the coax.

my high voltage generator creates 190 volts; as limited by two 95V neon bulbs... so once the bulbs come on, we're good.


My nano pulser itself pulses pretty well... sorta. 


During setting up this, I had a couple high voltage potential area where some wires were closer to ground than others.  I have oscillations of 200 some volts on the L2... it's got a ring-down though... so it has a higher frequency wave that's some 20 volts maybe?  I don't recall...  still playing really...  at a certain place if I stuck my hand through a loop and touched the plate of the breadboard which isn't a ground, it's just a mass... then voltage would develop on the neons... fun stuff


Okay; and I found some diodes for 400V 12A or whatever they were; and missed a coil, so added the coil between there... but the current of high voltage I'm generating is not high enough... I'm actually running on less than 100mA to get an optimal high voltage.  running at probably 25% duty cycle


So then there's this nano pulser; with the cap and resistor to the base of the high voltage driver transistor, it makes the pulse like 2ms; and I just don't have that much high voltage available... maybe it's a tiny cap


But also by the time it gets to the driver it's a really noisy signal ...

nevermind; I fried the chip with a diffeernt power supply .





okay so it's not a fault of the pulser noise I think; what I do get is through this  FJL4315OTU
http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/FJL4315OTU/?qs=ljbEvF4DwOMFc6Yt2N1Y8g58tzpPa9MR





This transistor I used as a replacement for the KT926 (200V(c-b) (unspecified c-e)  25A/5V(e-b)  50Mhz?)

FJL4315OTU (250V(c-b,c-e) 15A/5v(e-b) 30 MHz ) 

the E13009 is 400V(c-e) /700V(c-b)/ 9V(e-b)  (4Mhz)   


---------
Okay but the question is, if I apply positive voltage to the collector and ground the base and emiiter, current flows through the collector.  (if the base is low, shouldn't it not conduct?)


so the voltage should build in the capacitors behind it, except where the neon is, which limits the top voltage... but it's not static voltage, it must get current from the base  or emitter to conduct and make a signal in the coil it's attached to.


NPN doesn't conduct until a voltage is applied?  ... well it's a double diode right? so N-P conducts? no, becuase it's the base that's on the P, not the collector.  So ... it shouldn't conduct from base or emitter... maybe it's broken?  maybe it's got a fancy back diode in it?

Which schematic diagram do you refer to when you write this?
Could you put component references in your words, e.g.: the emitter-collector voltage of Q8, the current through D6, the voltage on C5, the turn-ratio of T3, etc...

@ all,

while still waiting for parts for the vco/nano-pulser, i build a small nano-pulser which was earlier proposed by verpies using a LT1073 dc-dc converter chip for testing the ability of my scope to "see" nano pulses.

Perhaps usefull for other builders to test their equipment as well.
