Eldarion and Bruce's build of Bob's Energy Converter

Eldarion,   to meter +   -------|<-----|<-------   to meter minus, the pickup or sample wire go's to the anode, cathode junction. As far as diodes or transistors go, I have tried the 2n404's , 1n4148 and 1n191 so far and found the 191 to be the most sensitive. But others can be tried. As far as meter movements go you can use 0 to 10 ua, 0 to 25 ua or in my case, I am using a 0 to 50 ua. The 0 to 10 ua meter and 1n191 diodes would make the most sensitive arrangement, might be too sensitive. Hope this helps.     Oh ya, Jason is trying to figure out how you came up with the 4x over unity for my little experiment.

When I was charging the 450 farad capacitor bank, the primary input voltage was apox. the same, current fell to 90 ma., apox. 4.5 watts primary input power. The observed charging rate was apox.  .4 to.5 volts per hour. I charged the bank over a 4 day period at 8 hours per day. That would be 36 watt hours per 8 hour charge period or 144 watt hours total. The capacitor voltage at the end of the charging period was 12.5 volts.

Input power:
8hours * 4days = 32 hours = 115200 seconds
115200 seconds * 4.5W = 518400J

Output power = 0.5 * C * V^2 = 70312.5J

So the COP is actually 0.135!!  Sorry, not sure what I was thinking earlier!
(Probably forgot one of the multiply by 60s)

I'll try the LEM detector next and try a Tesla type system to convert LEM to TEM.

Bob, Rich,

Do you have any ideas on how I could try to see some anomalous effects (other than energy gain)?  I tried setting the frequencies to F1 210KHz, F2 105KHz, and F3 52.5KHz in rotational mode, and adding 0.5A of magnetic bias along with 160V of HV potential, and let it run for 10 minutes or so, but nothing seemed to be happening.  I also tried the same thing with F1, F2, and F3 all at 210KHz, but nothing interesting there, either.

I can't help but think that I should know when this thing kicks into anomalous mode, regardless of LEM output, based on energy out and anomalous effects starting, especially with a system this powerful.  Am I right?

Bob, if you like, I would be willing to loan my controller to you so that you could mate it up with a known-working coil and see if it is the controller or the coil that is the problem...

The only thing I have noted as of yet is that I can vary the primary drive frequency all I want, and to some extent the pulse width, and no matter what frequency I use the HV back-EMF pulses on the primary always occur at 10uS intervals--even when there are drive pulses in between the observed back-EMF pulses!  Also, they are a bit odd in shape, perfectly symmetrical about a peak and there is no indication of ringing.  I haven't really seen that in any other inductive system.

So, any thoughts?   I personally can't help but wonder if the three disconnected primary windings are somehow interfering with the rotational field, possibly by creating gaps in the field patterns...

EDIT: Further thinking and musing about the field patterns has yielded an interesting idea.  I will elaborate futher over the weekend when I have more time (and test it as well! )--suffice it to say for now that it involves driving all six primaries in rotational mode just as Bob said, but with an added criterion.  If my thinking is correct, this will reduce my IGBT-frying back-EMF considerably, while allowing energy to build up in the core over time, as well as possibly explain why the avalanche mode happens so infrequently and unpredictably.

That sounds like an indication of a parasitic oscillation with the driver mosfet. I fyou drive the mosfet with a low voltage then you can put it into an oscillation mode wher in the off state it till switch on very breifly at very regular intervals. I ahve done this myself -- the worlds simplest pulse generator - even simpler than blocking oscillator.
-or- it could be something else.

Hey guy's, here is a picture of the maxwell 2700 farad ultracap. Put a six inch ruler next to it, to show size. The next picture is the new black sand or hematite cores, one torus and two rods. I included the micrometals T650-52 core for size comparison.
