I've built several MEGs ... unfortunately none of them were OU ... so
I guess I am qualified to offer some opinions. :-)
I have QUICKLY reviewed the JMPulseCharger circuit and while it
appears to be a very efficient charger, IMHO, a charger is a charger
is a charger. You don't explain why you have chosen this charger so
I can't really comment on it for this application.
I have also reviewed your closed loop concept and definitely have
some suggestions to offer here. Per comments from Bearden and
Naudin, closing the loop is really really tricky and as I understand
it, this was and probably still is a major hurtle for Bearden in the
production model he is working on.
May I suggest that you concentrate on just getting the basic MEG
running, that is, getting the coils wound (insulating them
rigorously), the core assembled, the magnets tighly stuffed into the
throat of the core, the control electronics going and then carefully
selecting and testing the driver/switching transistor devices in your
MEG and tuning things. This is in a major job.
When you get all this done and do some testing in open loop mode,
THEN you can move on to trying to close the loop.
Just my two cents!!
I hope that you do indeed build a MEG and I hope that you report your
findings, be they for a successful unit or not, to this site because
that's what this site is about. We're here to learn from each
Very best and good luck!
