@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:

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.

The Relative Permeability (μ_r) of Itsu's toroid was determined to be ≈4700.

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.
