  [ferd] Energizing a tesla coil Inbox Forums Andreas Mon, Oct 24, 9:16 AM Hi all, I did some preliminary experiments to get into tesla coils and Don Smith stuff. I built a simple HV DC power supply constituted of a self-resonant HV tr Gerry   smokyatgroups@gmail.com   via  groups.io  Mon, Oct 24, 9:42 PM to  ferd Hi Andreas, As long as your pulse is relatively short compared to the expected ring frequency and the pulse rep freq (prf) is not too high, you should get some kind of ring from your tuned circuit. The only thing I can think of would be excessive damping across the tuned circuit. I would check the Q value. To do this, use a high impedance feed from a low value capacitor or high value resistor or loose inductive coupling into your tuned circuit. Feed in a continuous sinewave (unmodulated) CW signal. Use a high impedance scope probe across the tuned circuit under test, say using a 10:1 probe. Find the peak response frequency of the tuned circuit under test, note this frequency
