Infinity Coil

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 Y'all,

Got the new tougher parts installed.  The inverter circuit is working again, however the tantalum capacitors overheat and the performance falls off when they do.  I am kind of puzzled with this at the moment.  These caps I bought at a surplus store, and they are color coded.  I am not used to reading color codes on capacitors.  They are probably really old.  There is a color stripe which is supposed to indicate polarity.  So I figure that they overheat because I have them installed backwards, or they are not rated for the voltage I am using.  I am going to pick up some new tantalum capacitors today and replace the funny surplus parts.  Then maybe I can get on with the experimenting.

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

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...

nice work z.monkey. its nearly 20 years since i civil engineered in electronics, did it good then, but. I dont want to disturb, but might be you should go for the parallel setup of the secondary coils, in this way you might avoid this uncontrolled back emf that burn your circiuts. at least i think you then have a chance to study the magnetic behavoir of the ring until you figure out the beast.
blessings to ye all.

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...
