dear all,

I am too wondering wether it is possibel to drive a teslacoil with dc
and without a unaccurate sparkgab.

First: Would it be worth to try to rectify the output of a 20-25 KV NST
with High Voltage Bridge rectifier consisting of several 1Amp, 10000 V
diodes switched in series and feeding the HV capacitor?

Second:
does anybody know some scheme's for sparkgap replacement by HV-triacs.
This would be a great way to synchronize the 'gap' on the
resonancefrequency by for example triggering the triacs via shuntvoltage
of a (very low!!, high Watt) resistor placed in the primary circuit?

thanks for your reply!

Arwin.
