Solid state Bedini charger from John Peters

Hi niofox I had done this on a double coil bedini and my problem is that one of my coils was winded with a new bold and it became magnetized. So now it cannot handle certain high oscillations.
Maybe I have to wind it again
Ok I am glad that worked for you too.
Thanks

Hi guruji,
How long did it take to magnetize?
What was your core made of?

Right now I'm using copper-coated welding rods that are pretty much the same as what was recommended for the ssg.
Before I took out the rotor there were times when I would leave it running overnight only to find the rotor stopped because the coil moved closer and stuck to one of the magnets.  This happened a number of nights and yet the core did not become useless nor did it seem to degrade in performance as far as I can tell.

I would be very interested in finding out if this high oscillation might have a greater magnetization effect

Thanks the heads up!

Hi Niofox if you did many rods of soft iron don't worry it would not magnetize. There are guys who did nothing for core just left an empty spool and found it better.
An idea came to my mind to change polarity of coils;now it doesn't effect knowing the fact it's without rotor
Yes if it's in high oscillation it would magnetize a metal rod faster I believe.
Ok lets keep charging
Thanks

I have removed my core and restarted the charger.
It still works, battery is charging

I will monitor it for a while to see if it is better, but it definitely seems to be running at least as well just looking at the voltage rise over a few minutes
More on that in a few hours

Hi Guys,

Do you mean that substituting the 1N4001 (transistor base-ground diode) with a 10K resistor and adding a 20k resistor between base and collector could 'work' (= self oscillate and charge another battery) in a 'standard' SSG having his rotor removed???

Or, I'm I missing something??? Core removed?

I have to try it on....

Very Best
