Tinman,

Have you been connecting one of the scope probe grounds to the drain of the MOSFET in all of your tests (or just the recent ones)? 


As for verifying the flat line -DC offset observed at the inner secondary during the off period (what you highlighted in red in my previous post), if you would indulge me perform the following test: 

The following assumes you have verified that there are no significant leakage paths between the various windings of the XFMR under test (i.e., they have been verified with an ohmmeter).  In particular, ensure there is no significant leakage path between the external primary and the inner secondary utilized during the following test.

It also assumes that you have verified that the scope channels, with the vertical sensitivity set to 5V/div (I believe that is what you have been using) produce a zero volt display when the probe tips are shorted to their respective grounds (i.e., no weird offset observed in the scope channels). 

It also assumes that the scope channels are set to DC coupling, and that you have verified that DC coupling is indeed functioning properly by connecting a small battery across each channels probe tip and ground for 30 seconds or so to ensure that the scope maintains a steady indication of the DC voltage of the battery used.

(Your observed "effect" is weird enough to warrant confirming all of the above...)

Disconnect the inner secondary(s) from the drain of the MOSFET, only the low side of the primary should be connected to the drain.  Use the BATT- as the common for the FG ground.  Connect one scope channel's probe tip to the MOSFET drain and that probe's ground to BATT-.  Connect the other scope channel's probe tip to one side of the secondary under test and that probe's ground to the other side of that secondary.

Set up your drive signals as you have been doing so that you are confident your FG settings are switching as in previous tests and that you are producing the flat line -DC off set on the secondary during the off period. 

Once you are satisfied the circuit is performing similarly to previous tests (i.e., demonstrating the flat line -DC offset at the secondary during the off period), disconnect ALL scope probes AND scope grounds from the circuit, including your external trigger connections.

With the inner secondary being tested still completely isolated from all other circuit connections, connect a lamp across that inner secondary.  Attach one channel of of the scope across the lamp, connecting the probe tip and probe ground directly at the two lamp connections.  You can just trigger the scope from that probe's input channel.  Other than the lamp and the singular scope probe/gnd, there should be no other connections to the secondary.  As well, the scope should also have no other connections to the circuit, just the one probe/gnd across the lamp connected to the secondary.

If you continue to see that flat line -DC offset on the secondary during the off period, connect the scope probe (still connected as above) to the other scope input and with that scope channel set similarly to the first channel used, note if there is any observed difference in the waveform.

(Alternately, you could just connect a second probe across the lamp (paralleling the first probe/gnd) and connect the second probe to the other channel of the scope so that you can look at both probes/channels at the same time to observe any difference).

Please post your observations. 

Thanks,
PW

I think the next video(which is uploading now) will sort it all out PW. If your still not happy with the result's,then i will follow all the instructions and measurements above.

Now,below is a scope shot showing the current flow through both secondary coil's. Can you guess which scope trace is showing the current flow of the outer secondary,and which is showing the current flow of the inner secondary. This shows that i am using DC coupling on the scope,or both traces would show the same-but they do not. The CSR's being used are two 2.2 ohm 1 watt resisters-one on each output of course. The loads are the two identical globe's you have seen in all the other video's.

So a little design tip is that you want the diode anode to connect as close as possible to the MOSFET drain, and at the diode cathode you want to add a capacitor connected to the MOSFET source, all with minimum area loop from the MOSFET drain through the diode and capacitor back to the MOSFET source.  The connections off to the coil aren't that important other than from a radio noise standpoint, which you can suppress by tightly twisting them together.  Then you want to put the scope grounds at the MOSFET source.  Then you want the signal generator black lead to connect as close to the MOSFET source as possible.  If you take all of those measures, then your falling edge waveform should clean right up.

Thanks Mark,i will do that.
What size and type of cap?

[tinman]

All
I have to ask. Looking at the last scope shot i posted above,and throughout all the video's-->what kind of a magnetic field can produce such a steddy current flow in one direction?. It is almost as though(well it is)the magnetic field is producing a DC current without much change in value.

I have a theory on this,but dare not say it,as you lot will probably ship me off to Theo's magnetic vortex thread 
But look at the depictions of the magnetic field around a toroid-->is it possable that there is a magnetic spin,and that spin is continuing in the center of the core?. Could this spin be racing around the inner windings of the inner core,and some how draging the electrons out of the copper wire-much like undoing a nut from a bolt,where the wire is the thread,and the magnetic field is the fingers that are turning the nut?. It seems much the same as winding up a spring(when current is applied to the primary coil),and then when the primary coil is switched off,the spring is unwinding.

@TinMan: Thanks for providing those two recent scopeshots for Test 1 and Test 2. They are making sense now.

How, exactly, are you "turning off" the 50 ohm output impedance of your signal generator, as you said in a post up above?

Before we try coming up with explanations of the phenomenon you've noted, we have to be sure it's not due to some problem with the circuit, like a leaky winding, a scope bug, a measurement or interpretation error, or some other "gotcha". Once we can be sure that it's real, that's the time to start considering, and trying to rule out, various theoretical explanations of it.

At one point some months ago, in a JT thread, we were looking at some similar indications of anomalous current shown on an Atten scope that turned out to be an error in the scope itself, but that was at a more sensitive vertical setting than you are using, so I doubt that the scope itself is causing the readings that you are seeing. But just to be sure it would be good to run the tests PW has suggested to make sure that your scope isn't "lying" to you.

I've built a driver circuit using your schematic, but I don't have any IRF840 mosfets so I used IRF640 instead. This difference should not account for the difference in waveform behaviour that I am seeing, though, I should think. I did use 1n5408 diodes just as you specified.  I have been trying to get some kind of "baseline" behaviour using an unpotted toroid with just the primary (L1) and secondary (L2) windings, and a small 12 volt lightbulb load.

Here is some more testing i have carried out.
I to would like to know what is going on,so as i know what to look for if this comes up again. But at the moment,i just cant spot any mistake. I am about to go and conduct some of the test PW recomended,so we will see where we end up there. I am going to look more into the two diode setup you will see in the video,and compare that with what the globe should look like with that voltage across it. This will let us know once and for all if the scope is showing facts or some sort of artifact.
