another small breakthrough on our NERD technology.

@ Ground loop: did this circuit discharge the input battery ?
And this is circuit is more related to a Bedini technology...

If I may presume to answer this part of your post - Schubert.  It's the same principle as it uses CEMF - but Bedini's technology is related to motors.  Ours is entirely solid state. And if and when we configure in a motor it will likely to be rather different to Bedini's set up as I'm not sure that his system is the most efficient.  We're actually working on this to try and figure out how our SA's managed this.  If you check out Sterling's forum - you'll see that there's a closed loop application of this applied to a motor that generates INFINITE COP - with a megawatt output.

SchubertReijiMaigo,

Groundloop in one word, just like a plane spinning around on the runway or an audio amplifier humming because of
current flowing into a loop of ground wires. :-)

I would call this circuit Rosemary Ainslie technology because I use the switch configuration she made.

The circuit is also oscillating with a negative voltage bias on the mosfets, just as poynt99 predicted with his Spice simulations.
The core is a Metglas core and I have an output coil with a diode bridge setup to send energy back to the battery. Scope shots
show a nice clean sinus so there is no "voltage spikes" or "radiant energy" as people like to call it. So what we have here is an
oscillator that uses energy from the battery through the L1 coil. We use the L2 coil (with diodes) to send energy back to the input.
The L3 coil (all three coils is on the same Metglas core) is an auxiliary coil so that I can use energy from the running oscillator
to charge my 9 volt NiMeH battery when the circuit runs. See version 2 of the circuit drawing.

I do not know. I have discovered that all my lead acid batteries is bad because of long shelf storage.
I have one 12 volt 1,5 amp, five 12 volt 7 amp. and one 12 volt 60 amp. They are all bad and ready
for recycling. So right now I can't test this circuit on lead acid batteries, sorry about that.

I have one 650 Farad 2,7 volt Boost capacitor that are OK. I will charge this capacitor to 1 volt
and test on the circuit. I do not know at this time if the circuit will run at so low voltage.
I will report back when this testing is done.

Groundloop.

@All,

OK, I did charge up my 650 Farad 2.7 Volt Boost capacitor to 1.2 Volt.

Connected to circuit, plugged in the 9 volt battery, did get an oscillation,
checked with a o-scope over the L3 coil. See attached image. Let the
circuit run. Measured the voltage over the Boost capacitor to be 1.191 volt 
after 15 minutes run time. After 30 minutes run the voltage dropped
down to 1.188 volt. The circuit still runs according to the o-scope.
After 45 minutes the voltage on the Boost Capacitor dropped to 1.185 volt.
So it is quite clear that the voltage in the capacitor is dropping over time.
I did stop the test after 45 minutes run time because the capacitor is
dropping in voltage and clearly discharging over time.

On the next test I will be using a 10uF 650V MKP low loss capacitor on the input.
The capacitor will be pre charged to 12 Volt before the test run.

[EDIT] The 10uF capacitor did discharge in approx. 1 second.

GL,

The 12V battery connection is a little unusual. You won't be able to get any appreciable power output from this connection, not that that was your intent.

I have redrawn your first diagram slightly (diagram A), leaving out the inactive Q2 MOSFET.

Try moving the negative of the 12V battery as in B and see if it still oscillates. This of course is a more conventional connection.
