Hi mex,

Ok, so you keep the voltage in the puffer capacitor within limits by adjusting the potmeters,  so the DC voltage would not go very high to damage the pnp-npn input transistors (because these transistors are also run from the puffer capacitor).

If you could suggest an isolating DC/DC converter circuit to Marius for looping his shown setup (the simpler and cheaper the better)  :D

Thanks,  Gyula


Hi Gyula!
 This is the circuit I'm using it right back so I can control the energy of the BEMF 4700uF capacitors. An oscilloscope can be easily measured in a series of low-value resistor, the voltage, the BEMF during the period covered, and the calculated efficiency. RESISTOR and D4 of the anode must be connected between the negative pole.
 The coils used depends on the setting of the potentiometer can be adjusted.

 BEMF will not be large, because the capacitor absorbs enough of the IRF and 9530 as we

 Hi Gyula!
Thanks for the reply!
I have a DC/DC converter and i'll try it as soon as possible.
I'll post the results

Hi Gyula!


Nice circuit, unlike the bedini drive circuit that uses a bifillar coil, your circuit is much simpler, and more adjustable by the 2 pots...


Hi Joefr!


if you put a load on the BEMF Recovery output would this affect the speed of the rotor beiing driven?

k well i tried posting my own topic but couldnt figure it out so everone on this link i need your help.ill try to upload my video let me know if it dont show up. (link to youtube)http://www.youtube.com/user/TheHighrollerscorp
 
ive been fightin lenz law for two years now and finaly i listened to thane heinz and his acceleration under load. i tried it and i think i got it to work using bedini motor im using 24 volt at 3 amps and hittin 2100 to 2200 rpm. then i have two generator coils in series with mu metal cores recieving 500 + volts at .8 amps.check out what i got and let me know if everything is good  and what i should do next .thank you

I finished optimizing this circuit on Sunday and I didnt have time to make more tests jet.


I will do some test regards speed under load today and post a video.

Hi guys!
I have a good news and a bad news.
The good news is that i have succesfull looped the bemf with the help of the DC/DC convertor without shorting or burning anything (thanks Gyula!)
The bad news is that the DC/DC convertor acts as a load and consumes power too.
I have to dig deeper

Hi Marius,
 
Yes, a DC/DC converter does have a "built-in" efficiency, the best circuits have over 95-96% efficiency, most simpler converters have a decent 75-80%, depending on loading current too (there is a maximum efficiency at a certain current value in the designed load current range for each individual converter).
 
So the "task" is to furnish in some extra output in your setup  8)   to accomodate the self consumption of your converter. Suppose your converter efficiency  is 80% [this is a COP of 0.8] then your setup's output/input ratio should be at least 1.2 (COP=1.2) to reach any possible self-running situation by the looping.

Hi joefr!


before I've tried the bedini as my drive ciruit, it ran great but when i connect a load or battery at the BEMF output or try looping, the rotor slows down...


I'll wait for your test results...


Good day! thanks...

Hi Gyula,


what do you think is the effciency of a simple transistor, zenerdiode and a resistor to make a dc to dc converter?

Hi Roller (haha), good work man, you definitely have the effect. You said in the post 0.8 Amps, but in the video you said milliamps. I hope its amps !

Would be good if you could buy a cheap multimeter so you can measure amps and voltage at the same time. Maybe get an analogue meter for measuring the current.

Also, what is the inductance of your gen coils or do you know how many turns and what gauge ?

I've been doing Heins' stuff for a few months now and got good results, using a single magnet on a shaft as a rotor i get up to 30,000 RPM which is good for the effect, as you know it needs high frequency and high-voltage coils. The videos that are called 'OUG whatever' are not mine i am archiving them :

http://www.youtube.com/user/deepcut66#p/u/7/onvYaT-k7yk

I'm now doing a multi-magnet motor like Thane's, and i'm switching over to a small electric motor instead of Bedini drive circuitry.

If you are having trouble starting your own thread do this, at the top of this page you have the Overunity banner, under that you have 'Home', 'Community' etc ..., under that you have the location on the website that you're reading "overunity.com > Community, blah blah blah, click on Community and that will show you the subject areas, once you click on one of those you will be able to start a nerw thread.

Would be good if you and i kept in touch as we are on the same path so i will definitely be active on your thread with my results and we can compare shit.


Thanks,

Gary.

Hi Gyula,

Hi crazycut,
 
Unfortunately,  it is the worst case situation here, can be anything from 10 to 90% depends on the voltage drop across the pass transistor and the load current. Just consider the voltage difference between the input and output and this defines the efficiency with the load current.
 
Only Switch-mode DC/DC converters can be considered for the higher load currents if you need efficient convertion.  The simple transistor, zener and resistor (i.e a linear regulator) can only be efficient, if their input-output voltage difference is only 0.5-1V DC, this means your recovered (and loaded)voltage as an input to the linear regulator is 0.5-1V higher only with respect to its needed output voltage (this output voltage then serves as the input supply voltage for your setup).  Just figure you have a linear regulator with say 5V voltage difference between its input-output and the load current is say 1 Amper, then the pass transistor dissipates 5W power on its heat sink and you have to make up for this loss in your setup.  (If you can manage the voltage difference to be only say 0.9V, then the dissipation reduces to 0.9W)

Hi Joe, DeepCut here from overunity.org.uk.

Gyula originally recommended this one to Romero :

http://www.maplin.co.uk/universal-3a-dc-power-supply-228639

Not sure how that compares to your two options.


Cheers,

DC.

Hi Gyula,

Thanks for the reply, I'd rather not use that ciruit, co'z im generating more heat and more input power, poor efficiency... :(

can you suggest a dc to dc converter ciruit that maybe a much better design to bulid? from where i live it's hard to find a ready made high efficiency converter...

CrazyCut look at the two posts above yours, ebay is the best place for cheap dc-dc converters.
