Excellent write-up on this. I'm trying to recreate your circuit and setup. Learn from it and then move forward from their. I had a few quick questions.
1. You said the voltage gets very high(225V) on the inductor. Why is this? Aren't we only pulling the LC circuit up to 5V?
2. The Frequency Generator that is running at 125kHz. What is the Vpp of the frequency generator? Is it 10Vpp or 2Vpp?
3. After I complete this test circuit, my goal is to design an effecient circuit that would allow a microcontroller(PIC) to controller the frequency and use feedback to adjust the frequency and make sure the circuit is always resonant. Any idea's on how to go about this? Possible circuit design? Thanks
I might be asking more questions later one once I get this design up and running. Thanks
