user TURBO?s replication of Steven Mark?s TPU ?

Will be interesting to see if Bedini will ever find a way to keep the radiant energy flowing continuously, so he can use it directly rather than just charge batteries.  Seems like he is taking the long route.

Capacitor is the collector per Bedini's explanations.  Transformer and associated components provide the pulses.  Slow repetition rate.

Anyway, as you all can see by now - this is not rocket science - just backwater science on a shoe string.

If he can dump the RE to a battery then you can imping it onto a metallic collector.  Perhaps he did not havbe the oscillation that SM mentioned.  Perhaps he only scratched the surface...

There's a real study in UnderUnity. How many times does an answer have to be mentioned before somebody does it? 

--giantkiller. Let's see what this week brings. Like whatever day really matters.

this circuit is not working !

an scr can only switch on !
Never off !!

The voltage must come (also via pulses) to zero before an scr go off.
Some of this circuits are "untested" ideas , without knowledge in
electronic parts and components.
(it is your time , that will be lost)

Hello all,

@Grumpy,

thanks for the pdf. Veeeery interesting.

Hi Pese and All,

With due respect, please have a look at the circuit again and notice the 3.3uF/600V puffer capacitor on the trafo secondary side, connected to the full wave bridge. The 3.3uF is a very small value capacitor for a normal puffer cap and can discharge easily into the very low impedance load, into the 2 batteries, via the scr.
You are right of course an scr cannot be controlled via its gate to switch it off and  here it is switched off when all the charge from the 3.3uF is transferred into the batteries, so the anode current of the scr goes down to zero, when the voltages in the cap and the battery become equal, ok?
From another Bedini yahoo group there was info that the 3.3uF cap charges up (it is allowed) to 24-25V DC under normal operation and this voltage goes down to the battery voltage when the scr fires.  The pulses from the NE555 come continuosly and their only task is to trigger the scr on.

So this circuit can work as is shown. Please think it over.  Usually there are lots of circuits on the internet which are 'bogus' or obviously cannot work. This circuit does not belong to them.  (and I am not a Bedini man of course to defend his circuits  )

Respectfully
Gyula
