Interesting experiment with an transformer, 2 lamps, diodes and an magnet

[GM]

@ Paul:
Thank you for the insight into "robbing kinetic & potential energy" and your elucidation
about this topic.
I know nearly nothing about magnetic domains within magnetizable materials, but it sounds
interesting. It is an interesting aspect that a change of the domain-alignments inevitably
cause a emission of energy.

Maybe the magnet in my setup will cause a faster re-aligning of the magnetic domains
in the toroid core and cause a higher energy emission - same way as you noticed in your
other post? Hmm, but why does it do not work this way with a coil on a normal ferrite rod?

Last night I came up with what I think could be breakthrough in how to extract energy
from the magnetic material. OK, I give my idea perhaps 30% chance of being error free,
but since your device and various others successful magnetic devices seem so similar
to my method I was excited to study your device.

Would you talk about your idea? Mybe we (or better all readers) could learn from each
other and enlarge our knowledge - unless you want to handle it as secret yet.

On #3 above you can verify this by wrapping a lot of turns of copper wire around a
large piece of hard iron such as a steel nail and connecting it to your speaker
amplifier. You will hear popping noises which are avalanches occurring within the
hard iron.

Yes I read about this "experiement" long time ago on a very intersting
website of two quite clever and striving guys from austria - http://www.hcrs.at/

Marcus, I am wondering about some other matches. For example, is your device more
efficient when using rods sa compared to toroids? Also, is your device more efficient
with material that is not too high or too low in permeability?

I tried it with a coil on a ferrite rod, but there is no effect noticable
(effect = increasing kickback energy while the total power consumption drops)

I didn't tried other toroidal core materials, because I own only this kind of ferrite
core. I think I can get a damaged PC-Power supply from a friend. So therin I will
hopefully find some other kinds of ferrite cores to play with (from the step-up
switching circuit).

...So I'll use LTSpice to build my circuit and see what happens. If nothing interesting
then I'll be glad to build your circuit.

I am very excited/wonder(?) on your results.

@Jason:
Your two cores looks fine. Please notice that I forgot the 5V voltage regulator in
my circuit diagram. Okay, It would work without it, but if you drive the circuit with
more than 12 volts it will damaged. The (hopefully last and) correct circuit diagramm-
version is online since yesterday. :-) I built the circuit long time ago, so I forgot
some of the modifications I made on the orginally circuit (which was a dimmer for halogen
light bulbs :-) )

@kingrs:
The modification with the antiparallel diodes in the circuit is still a mod made by me
(in contrast to my last statement). So I think I have to vet myself for 'Alzheimer'?
Okay, just kidding ;-)... but I am really stressed last time to manage the allday job,
the family, the everyday life under the aspect of my huge desire to go on experimenting
in every free minute!

I had an idea this morning while standing in the shower, as you do.
What about using a DC-DC converter IC and replace the standard inductor with the toroid
core and magnet. MC34063A
(...)
I have used the above IC and it works very well in normal mode, but I will try it again,
but with the magnet.

Rob, this sounds interesting, but keep in mind that the effect of increasing voltage and
current (when the magnet is placed) only occurs on the back emf of the coil! The normal
transformation will much less participate from this effect.
I don't know which exact signal-waveform DC-DC converter use for the transformation
(squarewave or sinus or something else), but I can't imagine that this converters are
working with the kickback energy of the transformation coils.

So you have to modify the circuit of the DC-DC converter. And maybe youl will result
in a circuit similar to mine.


But one word generally word from me to the Steven marks topic.

I don't think that this effect, which appears in my circuit, is the main secret of Steven
Marks device.
Okay, in his bigger devices we see similar cores with toroidial wounded wires on it, but
I think this only a clever (and maybe selfrunning) circuit to generate a signal wich will
be amplify by *somewhat* which *is* the main secret of the device.

I can't imagine that this two small cores in his 1 KW-device are able to produce so much
energy. The main secret lies in my opinion in the outher ring - which obviously does't
contain any magnetic material! Look at the videos - the big ring can be cutted by a
simple electro saw. There is no metall within.
In the videos some people handle with a big speaker magnet closely at the small black
toroidal device, but no attraction appears. So I think this device or core comprise not
from magenetic material.


Actually I (try to) read the 'monster topic' in this forum <The Master Of Magnetics
"Steven Mark">. Every day a few pages. At the moment I am at the spot where Steven
talks about his boss and the explosion of the TV-set with the marvelousness magnetic
eruption.

During sucking every kind of information I will modify my sight of the device a little bit.
Also the airly informations from Mr. Mannix keep my mind in motion.

So I think the main secret has rather to do with the way how the bigger air/corc-cored coils
are wound and how they are feeded with pulsing dc.

Hi Marcus,
As I undertand it, a DC-DC controller does everything that you are doing in your circuit but in one package.
It uses the back emf to step up the voltage.
I tested your pulse circuit in Electronics Work Bench and the mark/space ratio does not seem to work very well.
I did 555 timer IC circuit that seems to work better.

Try replacing your standard diodes with Schottky diodes as these have a low drop-out voltage and will make your
circuit more efficient.
i.e.

ST MICROELECTRONICS STPS1L30A Voltage, Vrrm:30V; Current, If av:1A; Voltage, forward at If:0.3V; Current, Ifs max:75A;
or
INTERNATIONAL RECTIFIER 30BQ100   Voltage, Vrrm:100V; Current, If av:3A; Voltage, forward at If:0.3V; Current, Ifs max:650A

I am looking at various controller specs at the moment to try to find ones that have a high efficiency and low operating frequency.
You mentioned 15kHz which is very low, most controller ICs seem to start at around 50kHz.
The reason for this is to reduce the size of the inductor, which in our case we want as big as possible.

I will try the controller I have at the moment and post my results.
Because the output voltage is fixed, I will use a fixed load and watch to see if the input load goes up or down when I introduce a magnet near the core.

Oh okay, it was new for me that this controellers use the back emf.
Thank you for this information.

Try replacing your standard diodes with Schottky diodes as these have a low drop-out voltage and will make your
circuit more efficient.

I already use low drop diodes (shottky, SB 130) with around 130 mV drop voltage.
But with an back emf of aprox. 42.0 volts it doesn't matter if the drop will be 0.7 volt or 0.13 volt I think. ;-)

I will try the controller I have at the moment and post my results.
Because the output voltage is fixed, I will use a fixed load and watch to see if the input
load goes up or down when I introduce a magnet near the core.

Fine, I am curious about your results.
Good luck and much success!

Hi Marcus,
Every millivolt counts.
500mV drop over 24V ~ 2%

The Schottky diode you refered to, is it made by Fairchild?
http://www.fairchildsemi.com/ds/SB%2FSB130.pdf

This has quite a large forward voltage of 500mV not 130mV.
You could shave another 1% off your circuit by using a better diode at 24V.
Check you output voltage, if your bulb is only 12v and only partly lit then you could be chucking away up to 5%.

The lowest forward voltage drop I could find at FarnellInOne (1056 diodes) was:
BAT754S by Philips, 200mV but only 200mA BAT754S by Philips.
DSSK 80-0008D by IXYS SEMICONDUCTOR at 230mV 40A, but only 8V.
20L15TSPBF by INTERNATIONAL RECTIFIER at 250mV 20A but again only 15V.

Here's one 1PS74SB23 by Philips 260mV 1A and 25V.

Rob,

Yes, your'e right. It is the right diode.
And you are also right with the forward voltage (500 mV acc. datasheet, but @ 1 Amp.)

I used this type of diode in another circuit. And I looked for a diode with
low voltage drop. I testes some diodes in this circuit and the SB 130 was one of the
diodes in my box with a quite low voltage drop (around 130 mV).
But not at 1 Amp, rather than 1-5 mA ;-).

I think this the reason for my "wrong" statement (wow, this time it was not my forgetfulness).

Bye Markus


PS: But first I will do some real and comparable measurements on the existing setup
befor I try other setups. I will do this most likely next weekend.
