Dave:

It's unfortunate that you don't even want to try.  The first thing you need to master in electronics is basic circuit analysis.

The two-liter bottles that you saw in the clip are capacitors.  They didn't state it to keep the clip simple.

A water coil is a hose formed into a coil.  Shocking huh?

Now you know what the water equivalents are for resistors, capacitors, and inductors, you can look at any simple circuit and imagine what would happen if you made it from hoses, resistors like you saw in the clip, open-top two-liter bottles, and coils of hose.  Do you have the mechanical aptitude to visualize the water flow rates and water pressures in a water circuit?  What is the equivalent of back-EMF or a forward EMF spike?  What's the water analogy for a Bedini motor when you disconnect the charging battery and the neon starts to glow?

Please don't laugh off what I am saying.  The water analogy is awesome for understanding and visualizing how circuits work.

I hope we change pages now and I will go back to the main topic.

I see you guys are posting up a storm about this on OUR.  BTW, the foil wrap around the transformer is just eye candy.  Itsu could confirm this by testing with and without the foil.  If the switching frequency is very high, then it may have some capacitive effects.  I am assuming that's not going to be the case.

I will comment on the annotated drawing.  I am assuming that the switching speed is high enough so C3 and C11 have very little ripple on their respective DC voltages.  Standard disclaimer, this would have to be verified on the bench and is subject to correction.

Case 1:  When the Stop switch is open-circuit.

When the MOSFET is on, the current flows through L1 and then through the MOSFET to ground.  This is the energizing phase for the magnetic core.  The LEDs may be lit from C3 still discharging from the previous cycle.  Note that in this case L2 has no effect on the circuit.

When the MOSFET switches off, the current flow follows the red path.  This is standard Bedini fare like I said before, with the addition of the big C3 decoupling cap to absorb the current spikes and convert them into the voltage that drives the LED array.  Not much exciting there.

Case 2:  When the Stop switch is a short circuit.

When the MOSFET switches on, L2 will output a DC EMF that is the duration of the on pulse.  The battery voltage plus the EMF generated by L2 (they add together) will then follow the blue DC discharge path on the schematic.  However, there is the 430 kohm resistor R2 in the path.  That's almost like an open circuit.  C4 will pass a tiny puff of AC current flow that will be absorbed by C3.  So there is a very tiny DC current flow and a little puff of AC current flow when the MOSFET first switches on.  The LED array will not light up, or it may be barely visibly lit.

Note that when the MOSFET is switched on the core of the transformer is still being energized and storing a significant amount of magnetic energy.

When the MOSFET switches off, this one might be an unpleasant surprise to some.  The current follows the green path.  There still may be some voltage in C3 that keeps the LEDs barely lit, but this has nothing to do with the green current path.

When you look at the green current path you notice that no energy at all is returned to C11.  All that happens is that the magnetic energy stored in the transformer core gets burned off in the wire resistance of L1 and L2, and the two diodes and the two resistors.  So when the MOSFET switches off, you get a "burn" and all of the energy stored in the transformer core gets turned into a puff of heat.

So to me, it looks like when the Stop switch is open-circuit the setup will be transferring battery power into the LED load and the LEDs will light up.  When the Stop switch is short-circuited the LEDs don't light or barely light and the circuit does nothing really except turn battery power into heat.

If here not fake. Author say, that core destroing after some time, after 3-5 days about, then need it reglue... So maybe he use frenquency, with that need put on self resonance on mechanical vibrations on ferite? And he also write, that wound need like in picture. And I, think, than shield of cuper not important. He also mention, that first thing, that ferrite destroy because shield make short turn, but, now he say seems, that ferrite destroing not of shortied shield resason, but it destroing by itself after some days.

Dear All.

I have made the simulation URL smaller as requested, thanks MileHigh !! However when I open the file I can't see the correct simulation. Does anyone else have any luck ?

Cheers Grum.

Grumage!

The simulation of your circuit runs!  I looked at it and I got it right in my analysis!  Woo!  Hoo!

Very nice job on the simulation BTW.

If some people are having trouble it might be because Java is not installed or it's blocked.  On my computer I have to click through three or four approvals before I run a Java applet.  That's intentional because I love to hate Java and Flash.  Flash is enabled of course because the Internet is infested with it.
