Ignition coil frequency
Your question JoeFR: "can car ignition coil work between 30-35kHz ...."
Answer: NO - because of the iron core
Measurement of a brand new standard ignition coil:
- quite linear behavior up to 5 KHz
- increasing output voltage up to a considerable resonant point 8KHz
- at 17 KHz back to the same output like 1 KHz
- above considerable decrease in output voltage
Conclusion:
- Best use for an ignition coil is the resonant point at ca. 8 KHz. We need to exceed 20 KHz (Tesla)
- Above use transformer with ferrite
@JoeFR: High quality work! I like it!
- Seems that you connected the bulb in parallel to the capacitor. What happens if you connect it to the other secondary coil (now open)?
- Conforming Utkin (see Patrick's online book) the cap performs the required short circuit at the operating frequency. Not shure if he is right. Maybe this coil/cap will run best in resonance mode. Conforming my initial measurements the cw/ccw behaves very unexpected and strange. On the other hand we expect it to not obey standard scinece
