In this thread we will discuss PFN's and if the VIC works like one.
Now Ronnie Walker tells everyone to study them. So I looked into them a while back, but didn't see the link. My first look was at the layout of the circuit, the arrangement of the inductors and capacitors. I didn't see any similarities. A PFN uses multiple caps and inductors in series and parallel. They couldn't be any more different. Plus the description, states that the pulses generated from the multiple caps and inductors form a single square wave type output with high current flow. Not what we're looking for.
So I took another look and noticed what was needed to get the PFN to work. It's this info that might lead to some new thoughts on how Stan's cell may perform as a PFN. In order for the PFN to work, the load and line need to be impedance matched. The line's impedance (coaxial), needs to match the impedance of the cell, for the network to perform as intended. Now what does that mean?
If we look at the VIC coils as the line, and the cell as the load, then these two items need to have a match in impedance. Now what does that mean? How do we determine the impedance of the coils, and the cell.
What is considered the impedance of the coils? Is it all the secondary coils? Secondary, positive and negative chokes? Does the primary influence the impedance? Is it measured when at idle or when it's working? In resonance or out?
How about the cells impedance? Is it just the measured reading or is it the readings when it is in operation? Again resonance? How do we measure it when it's working? Webmug has been taking readings with his set up when it's working, is that what we need?
Now because we have multiple coils on a single core, what about the mutual inductance? How does it come into play when we want to match impedance of the coils and cell? Again, Ronnie says to look at it also. Is it tested when at idle or resonance.
If the impedance is what we need to match up to get the WFC to work like a PFN, is that what is needed to make this work? Does the cells resistance, for the most part, need to match the coils? Is this why we need multiple tube sets in series, to increase the cells impedance, where a single tube just doesn't have enough of?
Lets see where this takes us. It's what Ronnie want us to research, in order to get this thing working, Let me know your thoughts.
