i confirmed this by observing the voltage across the emitter (ground) and collector.
The pulse went all the way to 0V

the transistor is fully open.
How could the the voltage between the emitter and collector go down all the way to 0V if the transistor was fully open ! ?
Did you make the Russian mistake?

I thought that was measured with toroid in place ... was it a resistor?

In some experiments Itsu was driving a purely resistive load and in other experiments he was driving a mixed series RL load.
However the VCE voltage does not provide reliable information about the saturation of the inductor's core. (IC does)

LOL,  probably, what i mean is that the Collector - Emitter voltage completely drops to 0V from 42V during the pulse (transistor conducting or transistor saturated).

That in contrary with the pure resistive load (the 4.7 Ohm resistor in the last video), where the Collector - Emitter voltage NOT completely drops to 0V from 12 V during the pulse (transistor not fully conducting or not fully saturated)

The difference is the pure resistive load (4.7 Ohm) only with low 12V and the combination of toroid (+ flyback) with 1 Ohm resistor with 42V collector voltage.

I will continue testing today.      Regards Itsu

In English, that means that the transistor was fully closed ;/

@all,

Did some testing with the KT926A transistor using up till 150V on the collector.
It had the toroid (6 turns) in series with a 1 Ohm csr and a scs106 Flyback diode installed.

It shows that up to 60V on the collector the base signal coming from the nano-pulser at max. width (765nS) is able to fully close the transistor.

So if i again modify my nano-pulser and use the 100KOhm pot (instead of the 10K now) perhaps i can increase the pulse width even more to fully saturate the transistor at even higher collector voltage.

Also a nice steady signal across the csr is there in contrary with the same signal when using the MOSFET.
It looks to me that at about 40V on the collector and 450mA Ic the toroid hits saturation.

By the way, see DSRD circuit experiments also here:

Hi itsu,

I think it is time to put all circuit together then see how it works with fully assembled 2 generators mixing on coil.
Also Dally did not had perfect nanosecond pulse I believe and he did not use MOSFET too.

Cheers!

@Itsu,

Is this the schematic diagram of your magnetic saturation measurement setup?
(BJT is exchangeable with a MOSFET in this circuit)

Almost; the probe tip /ground is reversed, so the probe tip is at the junction csr / filter cap, and the ground on the junction flyback diode / csr, see at 13:59 in the video.

@Itsu

It looks like you have observed saturation,  see the attached scopeshots.
The slope of the green line represents your unsaturated inductance and the slope of the yellow line represents your saturated inductance.  The blue dot placed at the knee of the current trace represents what is known as the "saturation point".

The slope of the green line should evaluate to 173μH (your 6-turn inductance) and the slope of the yellow line should evaluate to 30nH (as if the 6t winding was wound over the air, which has μr = 1 ). 
Unfortunately I cannot verify these slopes, because I can't see your scope's vertical & horizontal scales.

It is also entirely possible that these traces are curving up because of switching characteristics of the BJT, instead of the magnetic saturation effect. 
You can disprove this terrifying hypothesis by temporarily shorting out the winding/inductor.  When you do this, the current pulse should become rectangular, if the BJT is switching quickly enough.

Itsu,

Your CSR may be better set at 0.1R so as to increase the Q of the circuit.

I think its important to use a toroid as close as possible to the specified dimensions, making sure that the relative permeability is high. Do you know the RP of your toroid? It looks to be an iron powder type to me, which would have a low permeability.

It may not be necessary to fully close the transistor using a toroid with high RP in order to reach saturation. However, if the specified 1.5nF nano pulse cap is used, the pulse width can be widened so as fully close the transistor at a higher rail voltage than you are so far achieving.

Regards
Hoppy

I only query this as a coloured ferrite typically indicates an iron powdered core and these have fairly low permeability. Also 4700 seems very high. However, a very high permeability of 4700 would explain why itsu's core is saturating in this circuit at low voltage.

One of the most frustrating things in electronics has got to be the lack of a consistent, industry-wide color coding for inductor toroid materials. Almost every manufacturer has its own color code, so if you are presented with a random toroid, say.... pea-green..... and you don't know the manufacturer.... you might as well be colorblind.
And of course "ferrite" and "powdered iron" are two different things, and there are many different kinds of ferrite materials used in inductors. But you knew that already.

The other most frustrating thing is when manufacturers like HP or Tektronix use their own proprietary part numbers for common semiconductors. Drives me nuts.

Me too!
It even got to the point that I avoid products by manufacturers that do that, and encourage others to do the same.
