Effects of Recirculating BEMF to Coil

[gotoluc]

Hi everyone,

I made a quick change to the circuit this morning. I removed the 3 batteries in parallel on the flyback side and replaced it with a 30,000uf capacitor to give a large storage so we can tune the duty cycle and get our 12.95vdc with load (bulb) attached to have a comparison to the previous test 11.

It was so fast to see the results that even after 5 minutes it was obvious to me that there is a real humongous efficiency bonus using the batteries.

I had to stop the test after 1 hour and 40 minutes since the voltage on the source batteries started making large drops to 35vdc and climb back to 38vdc and back down again. I don't know what is up with that but anyways it's clear that there is an astronomical efficiency boost using the batteries in parallel on the inductive flyback side.

I hope others can replicate this so we can advance to an even more efficient way to use this effect. I'm now realizing that if I would of tested this method in my resonance experiments I may of had some better results. So many things to test now.

I'm out of the country for a week. Talk to you all soon.

Hi everyone,

I tried to replicate my test 12 video using a capacitor instead of the battery to try to understand why there was so much difference between the two tests (11 and 12) and I found out that one of my 3 batteries is defective and that was the main cause of the huge difference. So I deleted test 12 video so not to mislead anyone. Anyways, I'm replacing it with the one below.

This video demonstrates that a Resistor can attain the same amount of heat connected directly (no Coil) to the pulse circuit then connected to the inductive kickback side of a coil. Both tests were tuned to use the same amount of energy from the Series battery bank.

What I find interesting is, you would think that by adding a coil it would make it less efficient but it seems to be as efficient as without the coil.

So where am I going with this!... well, if we add a coil in the circuit and it cost nothing, and we can still produce the same amount of heat that's good! since the the coil could be doing work, like turning a motor and then the inductive kickback will keep the hot water tank hot or something of that kind.

Just sharing ... let me know what you think.

Welcome back and good video.

I think one question many will have is does the pulse driving circuit get its power from the same battery bank. That was kind of unclear.

I have a side question. How did you find the other wire end in that big spool of wire. I have tried finding the other wire so many times but could not on three of my 10 lbs spools but with much finer wire - 28-29-30 awg.

Hi wattsup,

thanks for looking and the welcome back

In all my tests the pulse circuit uses its own 12vdc battery which is still at 12.80vdc even with about 100 hours of use.

Some spools ship with both ends exposed and some not. One way or the other I should be rewinding this wire since in this spool configuration I'm fare from obtaining Maximum Inductance.

The performance should be better once redone. Here is a great program I found for calculating best spool or coil geometry for an inductance value. If you or anyone else know of another program that would work from a fixed wire length to give max inductance please let me know.

Thanks

Luc,

A battery's voltage is probably not a reliable indicator of the load it sees. I don't believe a battery's voltage drops linearly with load, especially if it is fully charged.

Get yourself a "current shunt" or "current sensing resistor" (both non-inductive) and use it inline with your battery supply. Use your scope to probe across this current sensing resistor to obtain the voltage wave form. Measure the duty cycle and voltage peak and calculate the power being drawn from the battery. That's the sure way and it "enables" you to perform measurements at the "next level".

I and others here can help you if you're willing to take this next step in your measurement protocol.
