I have to wonder about the Secondary coil on the twin core set up. Can we still conscider it Secondary to the Primary on a different core? In thinking of just standard transformer actions, L2 would first be a Secondary coil, and then a Choke coil after the secondary on core #2 sends out its voltage. This seems to me that there would be timing collisions in L2 from the current induced from the Primary through the core, and current conducted from the cell and second core and coils. In the twin core set up, L2 is supplying power to the secondary? In that case core #2 is really seeing L2 as another primary.
Are we in need of relabeling these coils to better describe their true functions? As far as I can make sense of it, core #1 still has a primary and secondary, while core #2 is two chokes with a diode in the middle, all hooked in series with the positive terminal of the cell and the start of windings of the secondary of core one.
I'm positive I'm not realizing something, but i can't visulize how a secondary on core #2 gets charged to a voltage with out being on core #1.
I guess starting with Stan's original coils on one core, I'd like to realize an order of operations in the transformer action. Simplified.., one pulse into the primary, and resulting action of the other 3 coils. Not counting resonance. A coil on a transformer core that is not a completed circuit is not seen by the magnetic flux in the core. Are the Choke coils seen as an open circuit while the Secondary coil is being charged by the flux in the core? If not, we are dividing the flux in the core between 2 or 3 other coils depending if there is a picup coil, which I would guess has low current draw. In that case, at a certain point in the order of operations, all other coils other than the primary are secondary coils. The Choke coils look to be opposing the voltage in the Secondary at this point. The voltage that the Choke coils produce in series, look like will over come the voltage of the Secondary. So hypothetically, if each Choke makes 10 volts for a combined series voltage of 20 volts, and the secondary makes 10 volts in opposing polarity, there will only be 10 volts left traveling in the polarity of the Choke coils.
