Hi Sephiroth,

I was just thinking of all my experiments with diodes and chokes on the Meyer WFC circuits.

The concept of the choke on those circuits is that you can really get very high voltage out the end going to the cell, while the magnetic field of the choke coil restricts current. The more winds on the coil, the higher the voltage and more restricted current. Those chokes are 10k ohms + so very high resistance but it is NOT the resistance that limits the current, it is the stronger magnetic field that limits the current.

Transformer secondary + -------> DIODE |> ----------CHOKE -----> Annode on WFC ---------> WATER ------> Cathode -----> CHOKE ------> Transformer secondary -

The chokes on both sides of the cell are wound on the same core.

Anyway, when the pulse is ON, the positive potential goes thru diode, through positive side choke and forward. When the pulse is OFF, the diode prevents reversal of polarity there and the charged field of the choke is discharged in the forward direction keeping the polarity the same as the terminals of the WFC (water fuel cell). When the pulse is off, the circuit is essentially OPEN so the charged choke's built up potential will discharge towards ground....moving toward negative.

The diode is what is letting your choke discharge forward to trigger the coil again and that is why it helped kick into self resonance I believe. I didn't think of this before but that is what I think is happening. A scope could show more detail what is really happening. Anyway, the diode to choke concept is also a frequency doubler in the Meyer circuit...two pulses FORWARD for the price of one.

I'll play with this concept on my oscillators because because it might be beneficial, I'll find out.

What was supposed to happen? I was just thinking of general benefit of being able to trigger the trigger while limiting what is leaving the input battery (current limiting)...but I guess without the diode is best.

If we can have some way of the SG triggering with little to no current, wouldn't that be best? How much current does the trigger take anyway? These transistors can switch with virtually no current. I had a rca 2n3055 oscillate while the input was 0.004 ma or 0.0004 ma's, literally and that was only a couple volts I believe. I have the details somewhere.

I think you could get it to work with no resistor...fix or variable...if the choke was big enough, which would be a matter of just tuning the choke to your application.

I suppose without the choke, if you know how much current the trigger takes at your max speet sweet spot, then just wind a choke to limit that much current...the voltage will still get through. [maybe a way to send the rest that isn't needed from the induction to the charging batt?]

Just an idea...you really got me wondering about this! lol
