There are so many things going on in the VIC despite there only being a handful components to it. I am still coming to recognize new actions in it. I am going to try to make a slideshow showing each component. But here is what I know so far.
1. Normally a transformer transforms power according to its winding ratio. But the other physical properties of coils cannot be ignored and they also apply to transformers.
2. Assuming point 1, we know we are trying to limit current in the VIC.
3. Also assuming point 1, we know we are trying to achieve a high voltage on the VIC.
4. Assuming point 2, two coils in the VIC can be set up to oppose each other to halt main current flow in the VIC. This will not completely stop current flow with other components but definitely slow it down.
5. Assuming point 4, since current flow is near possible due to restriction in point 4, applying a step up voltage on a transformer to the VIC, such as 5kHz will not do anything to the restricted current flow. Each pulse will just add to the magnetic field on the transformer core and leak some current out with each pulse since the current is being maintained due to what we know about coils in point 1. This will appear on a scope as a stepped up current, not stepped up voltage, at this stage. We are assuming the gate pulse has not been applied yet.
6. Assuming point 1, we know that when the applied voltage on the primary side of the transformer is stopped that the coil is going to want to induce a voltage high enough to continue current flow and we can calculate the required induced voltage to do this. Due to current restriction and high impedance on the secondary circuit it will be very high, in the range of thousands of volts. Since the coil that is coupled to the primary has higher windings, it will experience an exponential step up and could be in the hundreds of thousands of volts depending on the resistance it must overcome from what we know in point 4.
7. Since we know point 6, we can assume that if we kept turning point 5 on and off we can repeat step 6 over and over again. In essence, the gate pulse.
8. If we tune step 7 correctly, we can then get a step up charge on a specific component that has been placed in the secondary circuit, such as the WFC.
9. If step 8 has a resistance value, the amount of charge that can be measured will be lower relative to the value of the resistance. How high that value is is also dependant on how well the coils are tuned and gating of point 6 is tuned. However, this doesn't change the fact that step 8 is still being hit by potentially hundreds of thousands of volts.
10. Now, what if we got step 7 going as a second resonant frequency?
