Second Stage Joule Thief Circuits

[hartiberlin]

@Groundloop,
why do you use at all SCRs ?

SCRs are only mostly good in AC systems for e.g. dimmer circuits,
where the current goes to zero, when the AC waveforms goes through
the zero volt region.

Better use cheap MOSFETs like IRF 840 or something simular for switching
on an off the current.
There are some MOSFETs which have a very low RDon resistance.

Hope this helps.

i do have a mosfet circut or 20 lol

but this then requires a timmer or a freq genny .. 

this is fine to drive my convertor that takes the b cap to 120vac a few amps ... 

cuz we need 60hz banging.. or if a freq genny is used .. then you can set it what ever ac hz you want depending on the core  of course...

ist

this unit is fully showen public.. too .. even with the portection and recovery .. lol

many never saw it ...  ooo  well

  i think i even posted some where i even had my wires smokeing big time .. and glowing ...  all from a kick in the presents of a magnet feild and an electromagnetic feild ..

Stefan,

I used SCR because the low trigger voltage and current needed to switch
them on. The very low voltages in this circuit demands components that
can work at this low level voltages. I will find a solution.

Use a relay and op amp.Just as a test
Do not worry about the other supply current for switching the relay.

Most people will forgive you for that ..at this stage

Introducing other components to the supplies is asking for other effects any way.

THis is the only circuit that i have ever made that runs on .3 of a volt, interesting the way it reacts to slight change in the local magnetic field also.Lots of learning here

welcom mannix..!

happy you have had intresting results! 

i did do the 814 toroide ..  this is in my opinion a special unit.. 

they DO NOT GET HOT .. even run at a retarted speed!

now 2 of thease .. is important ..  thease operate a wee bit diffrently ... however results .. are based same as jt ..

those coils can deliver a bit of power ..  THIS IS WHERE ALMOST ALL FAILED IN THE PAST!

a lot of inventors that have things they dont understand .. and can not control it .. they have common problems like HEAT!    or they blow things up ...  i have over come all thease problems ..

1 the heat problem is because your banging too fast for the core material ..  why i chose ferroite

if a jt works at 1v and and 1 ma   and you can lite a few leds .. 

DO YOU NOT THINK IT WILL WORK  1 v 100a   hummmmmmm

and if it does ....     what is the point of amplification factor ... 

looks to me we will have increased from 1 ma 1 millionth of a amp .. to 1 amp  THAT TO ME LOOKS LIKE 1 MILLION TIMES THE INPUT ..  AND NOW 100 AMPS .. IS 100 MILLION TIMES THE INPUT ..

what do you think your .. out put might be .. 

this is long ago proven to be true.. 

ist! 

humans are silly ...  this is stupid simple ....   

anyhow   i have arc reactor designs ...  that i bet i can pull many kw from ... 

yes that is mounted to a PLASTIC RING useing plastic screws...
do not build this ... it produces X RA

aswell carbon is only good for the cold side ...  the hot side it burns up .. to NUTTIN....
a special high temp verry conductive metal is required then it MUST BE CONTAINED .. somehow..

left it alone ... i got better ways .. safer to the same ..
