Appears to be overunity Cicuit

[Spewing]

Thank you for clearing that up for me Mr.Entropy, i have learned a great deal from you, i knew ohms law but i didn't know how power was used, where was you at a few post back?

Thanks man!

Hi  Spewing and ALL,

this is a really strange circuit !

I am using an IRFP250 MOSFET and a regulated 14 Volt
Power supply and pulse the MOSFET with my square pulse
generator on and off.

The + 15 Volts positive side of power supply goes into the
low voltage transformer winding and
back out from the other end of this winding into the
MOSFET Drain and the Source of the MOSFET goes to powersupply
ground.
I have put 2 neon bulbs in series across drain and source, so this
saves the MOSFET from spikes bigger than about 160 Volts.

Now the 2 diodes at the output winding are VERY IMPORTANT !
Without them this is a normal transformer circuit,
but WITH them you get strange effects !
By the way, the big output cap could be scraped, you don?t need it !
This makes thecircuit much saver.

It seems that due to the 2 diodes, the circuit re-induces a spike back to the
input winding into the direction of the MOSFET.
This way, this circuit works up to 100 Khz !
I have as a load GU10 socket halogen lamps, one 20 Watts, one 35 Watts and
one 50 Watts.
The 50 Watts is the brighest, but also draws more input power.

I am using a 220 to 2 x 22 Volt transformer, where I did put the
2 x 22 Volts windings in parallel, so the winding resistance is lower
and I use this then to drive it with the MOSFET.

It really matters, how I connect these 2 coils in parallel to the MOSFET.
If you reverse connect the 2 coils , the effect is not there.
( I don?t mean to connect it, so the 2 x 22 Volts coils coils cancel each other
out, no I mean which coil end goes to the drain ofthe MOSFET !)

This is very important, cause the 2 diodes also only conduct
in one direction and thus it is inmportant in which
direction the primary 2 x22 Volts coils are energized !


Anway, I have about 0.7 amps input at the best setting at around 14Volts
DC input and my best GU10 bulb has about the brightness of around 10 to 15 Watts
I would say.

The amazing thing is, that if you short out the 2 diodes, then the input power
rises and you can only pulse the circuit to a few khz and then the light will
go out.
But if you leave the 2 diodes at the output in front of the incandescent GU10
bulb, you can switch to around 100 Khz and the light will stay on
with the same brightness !
Also the output wave is still a very nice square wave !

How could this be with a 50 Hz iron transformer ?

Well there is this pulse being induced back from the output
to the input and this somehow kills the hysteresis...

I have to study this circuit much more and need to take videos
and pictures, but now I am too tired, as I have worked on it now
for a few hours and have not slept the night...

Okay, try this circuit, it is amazing, could be an overunity
transformer, but I still need to do better measurements
of the input and output power.

Okay so far for now.

Regards, Stefan.

P.S. My circuit works better WITHOUT the cap in parallel to the
input coil.
Then there are more bigger spikes and thus the input
power also is lower.

But I must still try to do experiments with a different transformer,
which has a lower impedance in the input coil.
My 2 x 22 Volts coils in parallel still has a too high resistance...


It is amazing to see, that when you short out the 2 diodes at the output
with 2 small cables, that the voltage waveform
at the 2 x 22 Volts input coils is changing dramatically and you will be drawing
more input power.
When you don?t short out the diodes and leave them in the circuit,
the input power will fall and there will be a spike induced back,so the input
current falls due to this back spike, but the bulb does not change its brightness
much lower...so this back induction pulse seems to help the circuit save input power....

Regards, Stefan.

can you scribble down what your setup, if i understand you're using 3 transformers?

i used the ac capacitor at the primary of the transformer because it Drops Amps and it also makes the light Brighter. it appears to be resonating.

Okay, here the change to your circuit.

Look I have here 2 versions.

It really depends, how you hook up
the primary coil !

When it makes more noise due to
the core vibrating more, then it is the right version !
