Effects of Recirculating BEMF to Coil

[Kator01]

Hi poynt99,

yes.. what was the name of this band : foolish garden ?

it is very simple : they keep gullible people busy and attack those sceptics with a good technical background.
I have never seen such a foolish remark... actually too foolish to assume that it was
done unintentionally.

In the middle ages the inquisition-priests tested a suspicious person in an open court-session by touching the arm of the suspect with a metal bar. In the front of this bar embedded was a sharp thorn which was ejected a few millimeter upon touching the skin.
If the suspect person was screaming he was proven to be a witch.

Boy, our proposed methods of measurement gives proof : we are the wicked priests...

Poynt99, this thing is sort of developing into some sort of religion.
This sort of discussion-activities is a waste of time.

Silence ? !

Regards

Hi everyone,

a quick video update of the last test I'm doing before my trip out of the country this Thursday.

This test is using three 12vdc batteries in Series at source and 3 identical batteries in Parallel on the flyback recirculated side.

I find the test to be already demonstrating a good result compared to my previous test using only one 12vdc battery on each side.

It has now been running for 3 hours and the voltage at the series source is at 39.5525 and when I started the test they were at 39.7534. The interesting part is I adjusted the duty cycle to maintain the charge level voltage of the 3 parallel batteries with the attached load (bulb) and it has maintained 12.99vdc for the 3 hour period.

Once you see the video you may understand more: http://www.youtube.com/watch?v=g-XxgCtPtzI

Nice video as usual.

I am curious if you can try this.........

Do the same set-up but put only one battery on the output and add one wire going from negative of first series battery to the negative of the output battery, then put another wire with a diode from the positive of the output battery to the positive of the series battery that also has the negative. Try it, to see what happens, then move the negative and positive on the first series battery to the second series battery and see what happens, then move them again to the third series battery.

What I am thinking is if you have only one output battery to stabilize the output end for your bulb, then any excess can shoot back to the feed source via that diode.

Maybe one other note on the slow voltage drop on the feed side. Guys will want to make a joule calculation, etc., since those three series batteries do have a good level of energy available, but maybe with the above trial, the voltage will go down even less (or maybe go up) hic hic.

Just an idea. Always good work.

Hi wattsup,

thanks for the good suggestion I like it

However it will have to wait, since I'm going out of the country on Thursday.

I'll be back August 9th.

Thanks

Hi everyone,

last night I made a new video but could not upload it since my internet connection is down. I found a few free wireless spots so I was able to upload it today.

New Video Link: YouTube - Effect of Recirculating BEMF to Coil test 11

After I stopped the circuit and allow the batteries to rest for 2 hour the source series battery voltage recovered to 39.3958

and here are the individual battery voltage

Battery F 13.1249

Battery E 13.0817

Battery G 13.1894

and the voltage of the 3 Batteries in Parallel recovered to 12.99

This is all I can do until I return from my trip after August 8th
