Hi all,
I didn't know where to put this. I've been playing around with "Circuit Simulator", trying to make an inductive current amplifier. The circuit is quite simple, however after setting another inductor as a load it kicks itself. I need verification that this is just a bug because it doesn't seem like the 5v input will generate a run-away voltage like this. It builds up to 11Kv (11.32Kv*126.63ma=1.43Kw) before it stops the program. Also if someone has another simulator program to verify it (Spice, Multisim, etc) that would be great.
I've attached the circuit (ikick.txt) which can be imported at:

Thanks for any insight into this.
Hello all,
@DTB - to make it short
Is this a invertor in the schematic??

This is a boost converter with another inductor as the load.
You do know what an inductor behaves like right? It opposes instant current changes so voltage would be HUGE!!!

SO EM .. my large inductor of 5.15 henries and a aa battery .. what will the voltage be .. not kicking its self ... simply pulsed .. when 5.15 henries colapsed what is the output ... ill tell ya right now that .5 henries colapsed hurt ! and was way off my scope ... well over 1000v ALL WIRES ..
and my battery was really weak
try it think im kidding ?
ist !
I believe you IST, you can step the voltage up quite a bit with an inductor, even from an almost depleted 1.2 V AA battery.

thank you !
please anyone that trys this be carefull !
it bites bad !

Hi All,
@Otto, There is a digital inverter on the 2nd switch. First switch on 95% to charge main inductor and 5% on Second switch to dump into second inductor.
@EMdevices, This only works with analog switches. Put in a digital or mosfet switching and it doesn't work, you'll get maybe a 17-20v pk which would be normal for a boost. Maybe the sim is calculating transients with mechanical switching(?). The circuit I've been toying with is to charge a multitap inductor in series(mutual inductance) where each tap has a reduced inductance. Switch them down sequentially at high speed in parallel so that the field collapses down to reduced inductance, creating a large output which can be used for water heating. The input would be driven with solar panels (225watts) since that is the closest thing I have to free power when the sun is out.
@IST, This will work with a 30mv seed voltage at a lower output(according to sim) so an AA would have no problem. The analog switching would probably kill any gains though.

i agree unless you have a good cheep way to switch it high speed mechanical .. : )
i may have a method or 2 lol
ist
aswell if you used the rotation to move air and plunked a wind tunnel a top it .. you can grab from the moveing air too ... maybe a few computer fans ..
i have built and showen public a VERRY LARGE COIL built like i have explained for a huge pulse motor infact i built 2 of them bout 10 lbs each coil .. i have a verry large axel and bearing set and i have collected many microwave magnets to place on the rotor .. the mini stack can drive the motor generator and it will turn a FEW 12VDC ALTONATORS .. as well as all the other methods for generating large volumes of current !
Hi All,
Here is just a simple modification to the last circuit to keep the kicker energized I put in a 10nf cap. Now the sim just shows it go up(and up) over 50KW before it stops.
I will proto this up in the near future, power with a Jule thief, and definately check this out.
Seems like it would be fairly easy to build this or something close to it. Maybe just give it a real world try. I was going to try testing it in LT Spice but it doesn't seem to have an import ability. I may have another proggy that will do it - I guess the kick.txt file is what you would import?
you can always go optical switching but 5v is needed .. so you could use a jt and a led reciever on the fet but you may find a crystal diode is needed to get 5 v to fire the fet but then you just turn the jt or MOVE THE MAGNET ON THE IST WJT TRANSFORMER

@DreamThinkBuild - Hi. Interesting circuit, never came across it till now. I'm confused as to what your switches are! I had a go simulating with Spice, trying both reed switches & mosfets. Reeds were a no go, mosfets returned something reasonable when I modify the circuit a bit, (smaller inductor, bigger cap.) giving about 800V. No run-away effect like you're seeing! My effort isn't overly convincing though - selecting generic components rather than specific values like I've done returns something completely different! Anyway, fun to play with. I may even have a go at building it...
Hello all,
nice work here.
Maybe you should change the 7404 with a 40XX IC so you can use a 9V battery or even a 12V car battery? Just a guess.

maybe you use a atmega or atmel 8515 : ) and program the damm thing ... hummmmmmmm
ever hack free tv ?
: )
ist!
8515 is a 40 pin dip ... lol they make smaller ones for those that dont know it is a programable microcontroller
some are made hardned ! hummmm still it is a waste of time as i can do it with out junk spark gap the flb
get rid of the diodes you will blow them .. i lit 60 watt bubls from neo zapping alone and low self inductance . coils so do it right ... DROP THE 9VDC AND THE 12VDC ... AND MAKE IT RUN ON A WATCH BATTERY .....
HUMMMMMM
its all so simple .. use the watch battery to make the large kick .. from the several henry coils .. use the returned kick to power the low inductance coil then neo zap it .. then load it ..
and it is then posibale to start the coil with only the swipe of a magnet .. and a starter coil insted of the battery ..
where is the FROG NOW TO TELL THE WORLD THIS IS HIS WORK !!!!
I THOUGH SO ....
LITTLE FAG HE IS ... TRY AND TAKE MY HAT !
nuttin on the top but a bucket and a mop .. and an ILISTRATED BOOK ABOUT BIRDS ... see a lot up there but dont be scared WHO NEEDS ACTION WHEN I GOT MY WORDS !
http://www.youtube.com/watch?v=G7RbCyxU_Uc
HORUS!
i got a tonne of thease little light bulbs ...
this is what i was gonna do with em ... lol
i have probally 1000 of em 6vdc 25 ma ... lol use the mag synced transformer wjt take the output ... to the bulb then to the base of the fet ... build a second jt to fill the driveing caps to working voltage or use a cam board then fire the fets to a coil however your fets must be rated for THE FLYBACK VOLTAGE YOU WORK WITH OR THEY BLOW
drop a bulb on the output .. as your low inductance LOAD !
ist
the bulbs inductance as my meter reads it is 00.00 h
resistance of a bulb is 17.8 ohm
capatiance is OL over load
hummm
bulb is 120vac 60w
Hey DreamThinker
I looked at the circuit you presented. I cannot say for sure, but it looks like when the switch disconnects from the inductor, that it is singing on its own. I think that the program has a hard time with diodes and having disconnects with the diode still connected to the active passive device, the inductor. Probably in most circuitry, these situations would not be in place and all components are connected at both ends to some other circuit.
In your sim, the switch on the right opens, and the inductor should continue the current flow through the diode, but then it can not pull from the diode in the opposite direction, say bemf, if any energy is left after dumping what it had through the diode. But I seriously doubt that the inductor would retain any potential across its leads after the switch was opened. I am supposing here. BUT
Lets say that the switch opens, yet the inductor, with its inertia mechanism, forces more electrons than it has holes for through the diode to the source, and it may do so easily, being that the source is accepting all incoming.
Now, What might go on in the inductor, with its oscillations, if it had many open holes? Missing electrons. Would that affect the self capacitance and the inductance, and could it be an ingredient needed to pull from the vacuum? I never really thought of any of this before now. Im just spittin it as I type here.
Charge the coil as you show, then disconnect the coil from the circuit on the opposite side of the diode, and the inductor pushes many electrons through the diode and they cannot get back to the inductor. The coil should be 1 big positive charge just waiting for its babies to come home. Would it just be a static charge? Static. Is a positive electrode on a battery static when not connected to a load?
I would not put this one down till some experimenting is done, on a safe level. At first I fully assumed that when the inductor lost its top connection, that how could the inductor retain a potential across itself connected 1 ended to a diode that will only provide and exit and no come back.
Maybe the program does not know what to do with this rectified static, and it shows it some way some how.
I would say give it a shot. Start with low inputs at first and see what a couple pulses will produce.
If it is static, if you provide an earth ground with a spark gap to the static inductor, maybe the babies wil come home, except they will be someone elses babies. lol
I will post this on your thread and here at Energy Amplification

Hey dreams
I messed with your circuit with manual switches and could not get what I expected. I have found the program at times can develop a bug in the code if something goes awry during changes. Then I rebuild. If you save a code with a bug that develops, it will retain the anomaly.
Try to rebuild the circuit from scratch and see if there is a difference, being that you wont be making any changes and already have the correct values. Cus if you have a bug, and keep developing on that bug, all changes, like putting a cap on the inductor will still have the bug.
I would try the same from scratch and see what haps. =]
The main reason I think you have a bug in the code is the fact that the 1 ended inductor, when switch is open has potential and it is not really part of the circuit at the time. But my bugs are similar in that an unconnected leg can cause a funkyness in the code.
Good luck
