When designing a VIC its a trick of finding a middle ground between different values and variables.
You have to consider:
-Power (Voltage and current)
-Primary coil voltage
-Primary coil current
-Primary coil resistance to get desired values
-Secondary coil current
-Secondary coil voltage
-Saturation flux density
-core Al value
-Required L to achieve Fres at the desired freq
-Total wire length
-Number of turns required to achieve desired values
-Volts per turn if Vt exceeds several kV
-Minimum water resistance
And guess what, those are not listed in order (and I probably forgot one or two things), why? Because after you find one of the values you need you often have to change another to get that value, and then that changes and requires you to reconsider all the other values. This is no joke, this is serious and requires serious work and understanding....I spent 30-40 hours designing a VIC for the spherical resonant cavity and I just realized I have to start over because I made an assumption and took an incorrect measurement!
When people ask for the calculations I just shake my head. If you have never tried designing one by yourself you can't skip to step 10. If you try and skip to step 10 you'll never get it to work,
Dan, Thanks for sharing some really good drawings. Have you got a price quote to make an 11 cell resonant cavity exactly to Stan's spec?
