Hi all,
I'm back. I last left off with my VIC bubbling away slowly. Well after much time no change in gas output. I'm not surprised. So I took sometime off and did some reading on Resonant Circuits. I've purchased and read many books on the topic. (IMHO) By far the best book all around for this topic and many others is the "ALL New Electronics Self - Teaching Guide” If you are like I was and not following all of Stan's math pertaining to the VIC I'd highly recommend it. Good examples and lots of practice problems with answers. The ISBN is 978-0-470-28961-7.
After reading the book and now understanding what I'm trying to achieve looks like my current component Rf is either 1.1 KHz or 81 Hz. What's the big difference you ask? Well when I measure my WFC's capacitance with my AMPROBE 37XR-A it never produces truly steady reading but indicate around .65 uF. This with my total Inductor inductance of 5.88H for the Bifilar yields a Rf = 81Hz. When I now calculate the capacitance using Cf=KEoA/d I get 3.49E3 pF which with the same Bifilar yields 1110Hz.
If I bring the frequency down that low I have to back the input voltage way down as the current on the primary rises rapidly. So what’s next? I think I'm going to remove the WFC and just work on achiving a good resonance signal will a regular capacitor with a known value.
Thanks again,
bw
