Howdy Y'all,

OK, another test bites the dust.  Using inferior surplus parts apparently isn't going to get the job done.  The Infinity Coil is producing some serious Back EMF.  How much I don't know yet.  It is clearly over 1000 Volts because I was using 1N4007 reverse protection diodes which are rated at 1000 Volts reverse bias.  So I am going to spec some new parts.  I am probably going to remove the resistors that are in series with the Back EMF suppressor diodes.  Also I think that these diodes are going to need to be rated at a much higher current rating.  I hate to waste the Back EMF but I need to protect the silicon drivers.  This means I need to use some really hardcore transistors, like power MOSFETs or power IGBTs.  This means more expense, something I didn't want to do.  The plan is to make the Infinity Transformer as cost effective as possible.

Now there has to be another answer.  When Alfred Hubbard made this transformer there were no silicon parts at all.  So the question is how did he modulate the transformer?  Well, nobody knows.  I am trying to figure that out.  One answer maybe a modulated relay which mechanically switches the current back and forth between the sides of the primary coil.  Or there might be a motorized commutator which switches the current between the primary coil sides.  I am going to meditate about it for a while.  Maybe it will come to me in a pipe dream.  Who knows, right now I am damn tired and kind of pissed off that every piece of silicon on my new board is blown...

Howdy Electrodiode,

Yeah, inductors do temporarily store energy in a magnetic field.  However as soon as you remove the charging force they will discharge.  Capacitors are the antithesis of inductors, so if you put an inductor and a capacitor in parallel, then apply an alternating voltage they will oscillate like in a tank (radio) circuit.  My original hypothesis that the Infinity Coil was a self sustaining inductor device proved to be false.  A system is needed.  You need a storage battery, a way to modulate the transformer, and a way to rectify and filter the output current to recharge the storage battery.  The basic idea was correct, but the original impetus was incorrect.  The refined ideas are getting closer, but there is still a lot of development to be done.  Like Edison said, "Invention is 1% inspiration, and 99% perspiration" was completely correct.  Research is the 1% where you come up with an idea.  Development is the other 99% where you turn the idea into a reality.  Development is a arduous process.  If you can make it through development the you have earned the rewards that should follow.

You are right about there needs to be electricity to perpetuate electricity.  You only need a spark to start, but with the right device it should perpetuate itself forever.  The trouble is building the right device.  An inductor, even a superinductor will not do it by itself.  It requires an efficient system which can correctly utilize feedback from the output and simplicity is key to reduce resistive losses.  This system requires the original impetus (the battery), a modulator, a super efficient inductor system, and a rectified filtered feedback system.  It is not just a simple thing.  It requires advanced physics and some help from things that we don't completely understand yet.  I believe that the unknowns conform to Soft Particle Physics, but then again I have yet to prove that.

At least I have seen some promising results today, even if it only lasted one second before all my semiconductors got vaporized.  The next test will go better...

A lot of people were blowing up their inverters with that circuit.. I think you just need a better inverter.

I think what you are experiencing is not back EMF but flyback which is basically a field collapse trying to return to the energy source via the positive.

If you are using a battery to run the unit, put a wire from the primary positive(s) to the battery positive. On each of the wires put a big diode that points towards the battery positive. Meaning current can go from the primary to the battery but not the other way around. Now your flyback will have a good home to go too and the battery voltage will not drop as fast, maybe even not at all. You may be surprised.

For the diode, I wonder if it is possible to find large zenor diodes at let's say 50 volts or even higher. This way the diode would only open when flyback voltages are higher and this will re-charge the battery.

Also, if you can find a dpdt relay that has a small coil that can be unscrewed so it can be removed. Then put the relay mechanism next to one of the 8 coil bolt head and supply dc to the primary of that coil to see if it will latch the relay. They could be used as a successive driving method if you had 8 of these relays with each one on the end of each of the 8 coils. This way, you energize the first coil, it latches the relay to then energize the second coil, and so on until it just keeps turning round and round. Use the center coil as the energy collector.

My main concern is the magnetic saturability (is this a word?) of the bolts used on the 8 coils. I wonder if they have enough iron in them, otherwise you may want to add 8 small magnets on one of the bolt ends to assist in the saturation.

I may be totally off base here but with such a nice coil set-up there are sooooo many possibilities.

Howdy Y'all,

OK, just got back from the parts store with some tougher parts.  I am replacing the 2N3055s with 2N3773s and replacing the 1N4007s with UF4007s.  The back EMF diverters I chose were relatively slow parts.  The UF in UF4007 stands for Ultra Fast (75nS).  The breakdown voltage on the 2N3773s is 100 volts higher than the 2N3055s.  So tonight I am going to replace the burned out parts on the inverter board with the new improved parts and give this configuration another try.  Hopefully the board will be happy, if not I may have to find a non-transistorized way to do this.

Howdy NerzhDishual,

Excellent!  It does look very similar to the Hubbard Coil.  I noticed he is claiming a 6X gain for each transformer.  Hubbard only claimed 3X from what I have seen.  Also the Courtier Coil has the outer coils wired in parallel, While Hubbard's and mine are in series.  The date on the Patent is 1932, 13 years after Hubbard's public demonstration.  I'll have to compare this to the other information I have.  Yes it does help.

Thank You NerzhDishual

Howdy 4Tesla,

I don't think the circuit is a bad design for medium power applications.  But my needs are heavy duty here.  The 2N3055 wasn't designed for inverters, but the 2N3773 is specifically designed for inverters.  I need to get better caps, then I think the circuit will work good.  It just needed a little redesign, you know that's what I do...

Howdy Y'all,

Thanks for the admiration onormanns.

Well, I have had it with power transistors.  I can't get the Infinity Coil to work with the inverter board.  The new parts work, BTW did have the tantalum caps in backwards, and the inverter board drives an EI core transformer just fine, but won't drive the Infinity Coil.  Grrrr....

So switching to a relay setup.  So rather than building yet another board I am going to fall back to the Digital Driver Board.  It has a driver circuit on it which is a IRFZ44, which should drive the relay good.  This board also has a PIC on it so I can program the frequency easy and get it really precise.  I'll hook up the relay so that it alternates the positive and negative of the battery on the ends of the center coil primary winding.  Yeah it is square wave drive but, well, you know I gotta work with what I got to try and get the Infinity Transformer running.  I have already spent a bizillion hours on this thing and I feel like I am running out of time.

BTW that inverter circuit works good once you hot rod it a little.  Getting the tantalum caps in right helps too.  Maybe that one will be good for a DC to DC converter or something.  Its good to have some spare power converters laying around anyway...
