Second Stage Joule Thief Circuits

[poynt99]

I would encourage you, and anyone else interested to have a close look at the attached pdf document, which outlines in greater detail what I mentioned in my previous post.

In summary, it appears you are shuttling energy/charge back and forth between two capacitors, and there is nothing too novel about this. Done with care, one can achieve quite high efficiencies, on the order of 95% or so, but it is in no way OU.

Read the document, it is relevant to the topic at hand here.

PS. Sorry I had to zip it as it was slightly over the 300k size limit when uncompressed.

pony you suck ...

i have explained it as have others ...

i can put 500 1000v 1amp bridges on 1 coil ... 

my coils are tuned ...

and i can fill 500 caps ...  from 1 aa




do you know how .. ?   you should by now ....  i only explained it many times ... 

pony  you want something you cant explain ... and i already have ? 

go build otto adv !    and if it burns your house down cuz it ran away on ya ... dont come crying to me ... 

as above so is below  as is below so is above ... 

now go ask why i have done what i have ... 

i like earth not so crispy ...    ya know....   

silly humans ...

@gadgetmall,

I have looked into your proposal of an automated discharge circuit for your setup.

The Cadsoft Eagle design files can be found here:
http://home.no/ufoufoufoufo/JT-01.rar

First I must stress that I have not yet build this circuit, but it may work as planned.

Here is how it is supposed to work:

The JT runs and charge up the super capacitor. When the voltage over the super cap
reach 2.6 Volt then the SCR (T1) will get enough trigger voltage and will start dumping
the charge in the super cap to the load. Since I have tried to make this circuit KISS,
then the continuous current into the load must not exceed 5 Ampere. When the super cap
charge is gone then the SCR(T1) will stop dumping charge to the load.

Now the other SCR(T2). When the voltage in the PWR battery starts to drop under a
preset threshold (R4) then the SCR(T2) will dump some charge into the battery. When
the PWR battery gains voltage then the current through the SCR(T2) will be gone and
SCR(T2) will stop dumping charge to PWR. This will keep the PWR topped up at all time.

Can you test this circuit? If it turns out that it will work, then I can order some pcbs
for us to make a proper good looking circuit. If you do not have the TIC106's or is not
able to find them, just PM me an snail mail address and I will send you some TIC106.

Alex.

gl wow!

you rock ... 

dont waste time like the fools ...

the sad part i solved all this with out running many coils ... 

now i look at others work and tell them where they went wrong 

or offer congrats  !  or i scratch my head till i figure it out ...

William,

Thanks.

We will need this circuit also. If it turns out OK then I will make
enough pcbs so that many people can replicate this.

Alex.
