Shorting coil gives back more power

[baroutologos]

Hehe, looks like you catch the drift
And as always, DO NOT TRY THIS AT HOME

Hey,

have you any hands on experience with that concept?
have you ever assembled any device based on the shorting concept or gradual-shorting/  unshorting concept or just you are theorize.

We must have a vivid idea of what it is being discussed here.

Thanks

Shorting/unshorting yes, gradual-shorting/unshorting no. If you do not like the gradual concept feel free to forget it, after all there was "DO NOT TRY IT" disclaimer, and I meant that

For those who like the concept and do not read disclaimers... I guess without experiments we cannot move further on this. I feel we have almost all lego pieces but do not 100% know yet how to put them together. Progress is like a spiral you know, you can see the next wind but no straight way there.

I agree.  I ran experiment the other night with Joule Thief over on OUR , but I'd like to do some coil shorting experiments.  I think it will help with my Boyce TPU replication.

Speaking of HV experiments, how do you guys deal with scoping potential output waveforms which might burn out your gear?

My frequency counter has max input of 30V, and my analog scope has peak of 1000V  (how do you guys keep from burning out your scopes / freq counters if you are dealing with 60V to 1000V P-P waveforms?)

Thanks,

Hi Romerouk,

thanks for all the details. I'm still experimenting with this. You said that the single magnet has to attract to the core even if in repulsion. Please tell if you get the same: let's say you have the 5 magnets + core in one hand and the single magnet in the other. If you approach the single magnet to the core even 10 or 15 cm away you can feel the repulsion. As you get closer the repulsion gets stronger till you get to about 1cm, there the single magnet seems to overcome the repulsion and starts being attracted to the core. There is a balance point right about there and this corresponds to minimum current draw. Move the single magnet in either direction and input current goes up.
Is this the same in your setup? 

You mentioned 58-60 kHz, did you mean Hz or kHz? I ask because even just going to frequencies of 20 kHz the magnets don't seem to have the slightest effect on the performance, like it would be without magnets (basically just a buck converter).

Also, what is your input power, maybe it only works above a certain threshold.

thanks,
Mario

yssuraxu_697,

You leave the impression that you have done a lot of research in this area.
Why not post some results?
