Electromagnet power transfer question.

[nwman]

Of course I have another question.

Would it [if at all] be better to design it to produce an AC current like in config4 or to set it up to store the DC pulse in a battery and then convert it to AC? Would one be simpler to build/test then the other?

Is there any other problems you can foresee? Or does it simply come down to testing to see if the PM actually adds to the flux field of the EM?

It does.  But Steven already showed in his video it does, no? My previous letter showed a step further in separating input power from output power by referring the Bulgarian MEG setup.
Any pitfalls that may occur from now on, can only come out by practice. I am presently not aware of any more foreseeable ones.  Of course the usual, so far not mentioned obvious pitfalls like core saturation and loss are assumed to be handled correctly.

I think what could be done is to capture the flyback pulse at the input coils for further process to reduce input power comsumption and let coils C and D produce the AC, the frequency and the waveform of this AC may not be optimum for your load but I think they should be an optimum for the whole setup,  and solve the output AC to be favorable for you after that, independently from the setup.

Yes his video is fairly conclusive. However, as you can see I try not to assume anything. I plan on ordering parts next week.

Given the language barrier I can't read that site and I'm not too familiar with the concepts.

I think what could be done is to capture the flyback pulse at the input coils for further process to reduce input power consumption...

I am also not familiar on how this can be done. Do you have any links to resources explaining how to do this?

Thanks for the help,

Tim,   here is a member coming just in time: http://www.overunity.com/index.php/topic,5446.0.html

Gyila,

Thanks for the link. I'm still not sure how it works but I need to read into it more. Is capturing some of, if not all, BEMF "flyback" actually possible or is it still theoretical? I don't think it is nesisary in my design but if it would add to the effecincy then why not?
