I guess I was wrong about the frequency of the nanopulser...


In that I'm back to having no clue.
I got some alternate LSxx00's to try... but I couldn't get it going again.

That's why I'm telling you we don't have a clue about what we're suppose to do.
 
A friend of mine was working in the past with this types of logical circuits. When he was using a CMOS circuit to create an oscillator, for the same type of CMOS but different manufacturer, to obtain the same frequency of oscillation, he was using different resistors and caps. More precisely if the manufacturer was Motorola he was using let's say 12k for resistor and 1nF for the condenser, But if the manufacturer was National Semiconductors the resistor was 5K for the same 1nf condenser to obtain the same oscillating frequency.
 
At this moment we don’t know the frequency of the nanopulser.
 
I have made calculations for the resonant circuit L2 – 1.5micro and this are the results:
 
1 ----------------------------------------------------------------------------
Coil calculation
— One-layer coil a turn to a turn
                Diameter of former D: 46 mm
                Diameter of a wire d: 0.848 mm
                Length of winding l: 134.454 mm
=>Number of turns of the coil: 158.554
=>Inductance: 354.738 µH
2 ----------------------------------------------------------------------------
Inductance calculation
— One-layer coil a turn to a turn
                Coil inductance 354.738 µH
                Working frequency 0.0069 MHz
                Diameter of former D: 46 mm
                Diameter of a wire d: 0.848 mm
=>Length of winding l: 134.455 mm
=>Number of turns of the coil: 158.555
=>Q~ 41
3 ----------------------------------------------------------------------------
Contour calculation
                Inductance of a circuit: 354.738 µH
                Circuit capacitance: 1500000 pF
=>Frequency of a circuit: 0.0069 MHz
 
I don’t know what mutual inductance will really do this circuit, but I suppose that it will low down the resonance of the circuit. On top of that L2 it’s winded over L1, so the L2 coil isn’t really an air coil, it’s more like air-cooper (because of the L1).

Welcome back!

@All
What is this spiral transformer made out of coaxial cable?


К нагрузкe (to load)

Трансформатор импульсов тока со спиральной намоткой коаксиального кабеля. (Impulse current transformer with coaxial wire winding)
1, 2 - внутренний и внешний проводники кабеля (internal and external wire conductors); 3 - сборныe шины (collecting bus); 4 - срез oбoлoчки кабеля (wire jacket cut)

@all,

finally got my 74HCT00's, so build the VCO and nano-pulser.
Need some refinements like a multiturn potmeter, and another 5V regulator, but the results look good.

The nanopulse coming out of the pulser can be varied between 6Khz till 372Khz.
The width is 334ns at 5V.

I understand this width is OK as the final nano-pulse (1ns) will be generated by the next stage of transistors / diodes.

I like what you have done with that blue capacitor :)

Now the most difficult part is ahead of you. The driver for the DSR Diode and the diode itself.

The 74HC00 is fine for the monostable multivibrator but 74F00 or 74S00 would have been better because of their shorter propagation delay.
I don't understand why Dally calls the monostable circuit  a "nanopulser", if it outputs pulses that are 100s x wider than a nanosecond pulse.
The DSR Diode circuit is the actual "nanopulser", not the 74xx00 monostable.

Important advice: Make the monostable pulse width adjustable between 100ns and 500ns because the DSR Diodes work in that forward pumping pulse width range.

If this was not a replication of somebody's design, I would use another TL494 for the kHz VCO because it is more versatile and has stronger outputs. ...or better yet, one MAX5069 for the kHz VCO and the monostable, instead of the two 74xx00 ICs containing 8 NAND Gates for mickey-mouse logic.

The fast transistor driving the Tr1 primary shouldn't be hard to obtain. However the DSR Diode will be :(

The Tr1 core might be hard to match too (especially its saturation point), but maybe you will get lucky with that.  This difficulty is the reason why I am a proponent of driving the DSRD without a transformer and without ferrite cores.

P.S.
As always there are never too many parallel bypass capacitors on the supply rails and you might even insert ferrite beads or thick wire chokes wound on ferrite cores before the voltage regulators (in series), because once the DSR Diode starts kicking you will have a lot of nasty EMI.

Revisited my pulser circuit, I found several connections reversed, and one shifted by a pin, now mine works with adjustable frequency and yields basically the same result as Itsu :)  Although I can't seem to go quite so low in frequency...

Confirmed.
 
A friend of mine give me a russian K155LA3. Freqvency can be varied at list with this one from 4.2khz up to 410khz

@ d3x0r,    ok,  way to go 

@ mihai.isteniuc,  thanks for confirmation.

Thanks for the advices.


@ All,

for the nano-pulse part i aimed for the circuit as mentioned by "Сергей В." in his post #93 (see below) as it contains the most common parts.
However, my nano-pulse has flipped over to a non-nano-pulse (meaning inverted) when feeding to the gate of the IRFU320.
So i have a constant  14V on the gate (opening the MOSFET), and then nano width pulses to ground (closing the MOSFET).
This looks reversed from what it should be, right?
Is this a design flaw, am i not thinking right, or did i make a mistake somewhere?    Any thoughts, suggestions?

Regards Itsu

@itsuSo, as I understand that bit, the pnp transistors will be open without a pulse on them; and theoretically the voltage should flow through the lowest resistance, but over a time, a positive potential should develop through the 4.7 resistor and be seen on the gate of the npn... right?  It's not like 4.7 ohms is a total block compared to the low resistance of the other side?

Hi Itsu,
 
The way I see it: If you take into considertaion the other circuit with KT926, the pulse coming from the DD1 it's the one going into the base of KT 926 transistor. Basically this should happend here too. So you have to see where the things got drastically change in your design. On the base of the first KT 972 things should be ok. what,s happning in the collector of the first kt972? also in the emiter of the second kt972?
 
I will go with the simplest design (from my point of view) with kt926. But for the moment i don't have the time to finish this part. Still waiting for kd203a to arrive. Also i have to determine the permeability for the ferrite rings i have to see if one it's suitable, make the transformer with cooling oil and so on ...

Hi !
Would like to show my vision of Dally systems blocks.
I think this way its little easy to guess about how does it works..


Thanks

Your diagram is all messed up :) 
L4 is the output/load/input to dc-dc converter...
the dc/dc converter is 110/220->12v not the other way... so the 12V takes the place of the battery, this comes from L4 (what you have marked L3)
on t1 there's really 4 windings, the 4th goes to the top GEN2  (you have 2 gen2's)
