Romero's experiments and OU principles

(because rectification doubles the frequency)


neptune,  did you notice the above sentance in my previous post?     His FWBR rectifies the sine wave.  these are pulses into the output capacitor from all the coils.

P.S.   Oh I just saw your edit.   I'm glad you notice it, but good question none the less.

Perhaps you need to consider the frequency is on the AC side this is the bit that requires consideration.  As the magnet passes you get one sine wave pulse so therefore this is the frequency of concern as it effects what the cap tuning capacitor value should be AND it determines the ideal core flux material to provide max permeability without saturation or eddy current losses.  Whatever happens on the DC side is not so important except for impedance matching to desired load. IMO the frequencies we are going to be seeing here are best suited to Iron Powder Cores or metal alloys.

Hello friend, where can i get these small holeless ferrite beads in the uk?  i have taken out 1 of the same one from an old pc powersuppliy, but, i have looked on ebay maplin and everywhere and i cant get them.. :S

You can find them on ebay as pre wound "inductors" and just remove the wire.

Anyone know if Romero used some special wind on his coils other than the wire used?
I didn't see any capacitors directly on his coils but wasn't something said about this also?

sadly i did not find any small holeless rod types,  anyway, I just saw a picture from Romerouk which had coils and iron powder inside, can you, Romerouk, confirm that your effect worked with iron powder, will you?

...not quite 'everywhere' 

Farnell sell them - i got some 20x6mm OD 4B1 ferrite rods from them (they have a few other sizes & grades also)
