PhysicsProf Steven E. Jones circuit shows 8x overunity ?

[conradelektro]

P.P.S: When tuning the circuit we tested today at Per-Johan´s place, I saw, that it works like a Joule Ringer circuit.
Changing the Base current pot just changes the frequency of the Spikes and the waveforms looks very simular to the waveforms of a JouleRinger.

The 3rd coil on the core is the easiest way to get rid of the different DC level problems when you want to feedback the output to the input.

Regards, Stefan.

@Stefan: I like Per-Johan's idea (the third coil on the toroid). May be Per-Johan is willing to provide more details of his circuit (value of capacitor and resistor at the base of the transistor, which transistor, number of wire turns on the toroid).

Greetings, Conrad

@xee2: may be one can combine Per-Johan's idea (third coil on the toroid with full bridge rectifier) and your low power JT circuit in order to feed back power to the 10.000µF capacitor? This should reduce the power consumption even more.

  I found it!  I must say, Nul-Pts always provides intriguing posts, and I found this in a posting of his in May

Nul-points post, and if you care to comment further NP, I'm all ears!!

thanks for the kind words as always, Steven...

i'll just bask in those words a little longer - before having to point out that your quote about OU statistics must have been posted by someone** other than me! 
[EDIT:  ** it was by toranarod]

here is my contribution to the list of reported OU development, hopefully with a reasonably mainstream emphasis:-

energy calculation for 2 uA Joule thief:

10,000 uF capacitor
start voltage = 1.358
end voltage = 0.599
time = 84 minutes = 84 * 60 seconds = 5040 sec.

Joules = 0.5*C*(V1^2 - V2^2) = 0.5*10000e-6*(1.358^2 - 0.599^2) = 0.0074

watts = Joules / seconds = 0.0074 / 5040 =  1.468 uW

hi Xee2

this result based on a start voltage of 1.3V and an end voltage of 0.6V, along with the previous test runs we did from 1.5V (?) to 1.1V, really highlights how the power consumption falls with supply voltage

you can see that your initial continuous DC Power in at 1.36V & 2mA is 2.72uW, yet your overall average is 1.47uW

obviously the lower the end voltage, the lower the average DC power value that we'll measure for a particular test

hence Steven's guideline of a voltage range between 2.55V and 1.5V  for reference purposes (also, using 1000uF caps, for direct time comparisons, of course)

hi Conrad

the tertiary winding approach looks good, but my experiences with it (posted earlier in this thread, post #163, 3rd Jun'11) suggest that it's main benefit is in decoupling the pulse o/p from the DC biasing necessary for the oscillator
(see first schematic below)

the most 'efficient' config i've been able to achieve has been to use a different approach to Looping and DC Decoupling and remove the tertiary winding altogether
(see second schematic below)

utilising both +ve & -ve o/p pulses also gave an increase in input current draw, so having a FWBR on the o/p (with the additional loss in forward voltage drops of 2 diodes, rather than a half-wave rectifier) doesn't appear to be a good way to go (in this circuit)

hope this helps
