Hi Tao,
nice ideas with the 2 different flows.

You can see exactly here:
http://overunity.com/newman/arcing2.JPG
as the current is broken by the mechanical switch the DC input current
into my coil at 33 mA is broken and then a spark jumps across the switch wich
brings this negative current spike into the battery back.
Also the coil itsself has a huge radiant impulse in it and it is
radiated away from the coil and interferes all radio reception in the neighbourhood !

Here you can see the circuit diagramm,
but the switch in it should then be better at the negative side of the battery.

Here you can see a 2 trace scope shot.

The upper trace is the capacitor supply voltage at my
voltage doubler supply, ( low capacitance, so you still see the 50 Hz
supply ripple)

and the lower trace is the input current into the coil.
You see the 33 mA at around 620 Volts input current there
due to the ohmic resistance of the coil.
Now if the commutator opens, a spark occurs and a back current pulse
back to the capacitor supply occurs, which in fact does recharge the caps
so you see it in the upper trace the voltage rises over the 620 Volts input during
the back current pulse !

P.S: If I would have taken a 620 Volts battery instead of a voltage doubler feeded from the
grid the upper trace would have shown a flat voltage line and only during the back current
pulse the voltage would have risen....!

Stefan,

Regards to Newmans and noise, have you ever tried applying white noise signal to a transistor which pulses a large coil as marco has said?



Regards,


Dave.

No, not yet, what should be the effect ?
