TK:

Here is a little Easter Egg for you:

That was my Googlegasm experience.

Lol-nice one MH.
I know it wasnt quite as good as your copypastergasm,but thats all i had at the time.

Well
lets make it happen...

Count me in.

P.S.
If you want to buy a cheap good scope I recommend the Rigol DS1054Z because it costs only $399 and can be hacked up to 100MHz for free.

Looks like a winner!

I must have missed the bit about the ground. Is this one ground independant?

We have basically two different circuits that are being compared because one uses a deflection transistor driven from a function generator, the other (Itsu's) uses a FET and a FET driver chip buffering the FG.

Note that the transistor version will hit a limit of maximum inductor current when driven from the FG because of the limited current gain of the deflection transistor. (8 to 10). BTW this is a very low gain power transistor with built in damper diode.

For a proper replication by all Chris needs to find the current output and note the voltage setting that he used on his FG and the output impedance of his FG. He admits that he is driving the transistor base directly from the FG.
This accounts for the current limit of the transistor, not a total shut off but holding the inductor at a certain current level due to restricted base drive and low gain of the transistor and the high saturation voltage (5V). see attached annotated scope shot

Besides proper power measurement there are some interesting aspects to the circuit configuration that I will expand on in a later post.

For now it is important that Chris's original scope shot is fully understood, and that his circuit is replicated as closely as possible. This means using the exact 2sD1555 deflection transistor with built in damper diode or the closest possible equivalent.


Use of a FET will give very different scope shots versus the low gain, high saturation voltage deflection transistor. These differences must be fully grasped before a full understanding of the circuit operation is had.

In something of an analogy:  How much force does it take to stop a locomotive in:  An hour?  A minute?  A second?  A fraction of a second?

A decent power MOSFET can switch in 10ns to 50ns.  The new GaN MOSFETs switch in under 1ns.  If a MOSFET carryies current from an inductor, (and all conductors are inductors) the magnetic field associated with that current will when the path is interrupted cause a voltage rise without limit to sustain the current.  As the voltage rises, the current goes into parasitic capacitance.  This continues until either something conducts: an intentional clamp that diverts the current through a different current branch, or an arc forms, or the energy is transferred completely to the parasitic capacitance.  All boost, flyback, and derived power supply topologies rely on this behavior.  Kettering ignitions are examples of where the goal is to intentionally form an arc.  If an arc does not form at a low enough voltage the ignition driver can be damaged.  Flyback circuits go back over 100 years.  There is no associated free energy.

Old too is the idea of bucking coils on the same transformer.  Back before switching power supplies completely took over, multi-tap transformers were used to match up international line voltages.  In some configurations a 10V winding on the transformer would be wired to buck a 120V winding so as to get a 110V net winding. At mains frequencies there's no need to wind in different directions.  Just swap leads, connecting dot to dot in series instead of dot to not dot.  These practices go back many decades.  There is no associated free energy.

One can design coupled coils / transformers many ways.  The fundamentals don't change.  The hypothesis and evidence absent idea of overunity EMJ put forth is nothing more than a lark.

Excuse me. I don't understand one thing.Can you explain ? How is that possible that output of unloaded ( I mean a not complete circuit , without output diode and capacitor) of   flyback or boost converter are spikes of high voltage, in fact voltage that should damage output capacitor, yet when diode and capacitor is connected it immediately summarize to the output voltage much less then without capacitor ?
