Hi all,

Has there been any research that when you induce into a coil, a voltage with the coil at X inductance, and magnetically change the properties of the core during TDC in a generator, hence lower/or increase the inductance, does the core will give up a burst of extra energy.  That is you induce a voltage into a coil, then you change the inductance of the coil, does the output voltage change........some old article I read years ago alluded to this.......any ideas?  Very poor way of expressing it, but it is an idea and my terminology is lousy too.

maybe you're thinking of the "parametric conversion" experiments reported by Naudin?

some members here had also started discussing this as a technique, but i think interest has probably been diverted at the moment by something closer to hand! 

hope this helps

@LtBolo : nice, now let's not forget that the whole stup is balanced. That means the ferite cores atract each other in a way that the sum of pulling vectors is 0. That leaves back to the adjustment of the strength of the fields as key finetuning setting. The smaller the MF the smaller the drag will be, the longer the device will loop for a specific load.

In case, by accident Romerouk device setup was something similar like this : http://www.youtube.com/watch?v=kCr3lOhMJCg = non balanced setup !, where the merging point is actually the drive coil. Maybe he managed to finetune it to actually loop ?
( each magnet get attracted to the next ferite core a bit more then to the previous one. Though some say entering and leaving the attraction leaves you with nothing. Not sure about repulsion mode. if there was no washer and ferite i would say that the PMs on top of the coils were pushing the rotor magnets )

Not sure how many places romerouk stated this is a OU device, he did mention it runs for a few hours. That means it is very efficient dynamo ? I don't really care if it is OU, i like the whole experiment And i do learn quite a bit from it

About those rectifiers at the end of each coil series, if they would be only 1 way rectifiers ( half of the sine wave ), would that help the coil escape the drag ? Would it make the coil to become an open circuit thus not letting it build up a magnetif field in the coil to opose the PM leaving the coil + ferite ?

@Nali

Can you please measure conductivity on the DC2DC converter input to output. I would like to know
if it is galvanic isolated or not.

@nul-points .You beat me to it on the subject of parasitic oscillation . If you refer back to the thread I started , called" Overunity Parasitic Oscillator?" you will see that most of the designs mention use abrupt parameter changing by switching . If this device is using parametric oscillation . it is closer to an ideal design , in that the parameter in question , inductance , is changed in a "dynamic" or sinewave like manner .Hope that makes sense .
