Have not stopped working on VIC system I have been trying to figure out coils and capacitor relationship while I followed Ronnie’s explanation, I was missing something. It was not clear to me how he got the 2-volt difference between the inputs to cells.
I built my current set of coils following Ronnie’s post below. While I have the resistance close on each coil the turns ratio is not right. I knew that at the time and planned to fix it later as this set was to develop my skill in building the coils.
Interestingly, Ronnie’s instructions focus on resistance of coils and loads only. He explains elsewhere this is because when resonance is reached the resistance in the system still remains, so to get max power out of system you need to account for it.
As I am planning on only using six cells instead of 10, I felt I need to better understand why the coils are set up as they are. Ronnie stated you can scale system if you understand how this all works. So, I have been trying to increase my understanding. Read several articles and watched multiple YouTube videos most of them showed ideal equations only, but I did find a few that include resistance valves. Still, I was missing something.
Did not find what I needed until I looked at transformer articles. These had the information on finding turns ratio using impedance equations. This matched up to what Ronnie showed (posted his work below). The transformer articles also brought up the transformer voltage equations that showed the relationship of the number turns on the primary and secondary coils is directly proportional to voltage on primary and secondary coils.
This was one of pieces I was missing, if you know the voltage on primary you also know voltage on secondary and in our case also the voltage on chokes as they are all on same core. I know the VIC is more complex than that but the voltage difference across the two chokes can be set by number of turns using the turns ratio. Ronnie then says to take turns off one choke and put it on the other I to set voltage difference. (Ronnie’s post on this is also below.)
I took me a long time to feel confident number of turns in the Transformer equation for voltage is the same as the number of turns in the transformer impedance ratio. In fact, the standard notation for the number of turns is explained to not be a ratio.
The reason I was hung up on this is I found I could not measure the voltage difference across the choke so I did not know if I was getting it correct thing as I could not measure results. I did not understand the transformer voltage turns ratio when I first looked at this.
The thing that bothers me is the impedance turns ration includes all the resistance of all the coils, but it appears the voltage turns ratio 5.567 in Vic is only applied to primary and secondary. The chokes resistance values are match to secondary with turns adjusted to get voltage difference.
VIC I built is close as I wound the coils to contain the resistance from Stan’s coils. As wound the turns ration is too low. I looked at what it would take to fix this. Adding more turns to secondary and chokes would add a lot more resistance. However, if you increase the diameter of primary to reduce the number of turns you can raise the number without changing the resistance. This will not change resistance balance but will have an effect on impedance balance.
Note: Below I included thread referenced as it shows the load balance calculation coils.
