I still have not been successful in finding an active Tesla member here in Melbourne.

Hi Fred, Modern solid state TC's use a pair (half-bridge) or two pairs (full-bridge) of 1200 volt power switching transistors (most often IGBT's) to drive Mon, 03 Jun 2013 21:55:10 GMT McGalliard, Frederick B http://groups.yahoo.com/group/usa-tesla/message/26505 http://groups.yahoo.com/group/usa-tesla/message/26505 The spark gap primary must have a few KV across it. Large step up and some fun with resonance and we get megavolts at the secondary. Transistors operate Sat, 01 Jun 2013 12:58:19 GMT Saber http://groups.yahoo.com/group/usa-tesla/message/26504 http://groups.yahoo.com/group/usa-tesla/message/26504 It´s a little shame that my posting is greatly delayed like my latest one that was posted a very long time ago. Oh BTW, the whole deal about what I originally Thu, 23 May 2013 19:54:11 GMT Chris Swinson http://groups.yahoo.com/group/usa-tesla/message/26503 http://groups.yahoo.com/group/usa-tesla/message/26503 Tight coupled circuits are a "one shot deal", where primary and secondary are directly affected. Tesla coils at say 10% coupling, will just take 10 cycles to Thu, 23 May 2013 19:09:53 GMT Ed Phillips http://groups.yahoo.com/group/usa-tesla/message/26502 http://groups.yahoo.com/group/usa-tesla/message/26502 Set up the network equations with general coupling coefficient and solve. In a lossless system the energy flows back and forth between primary and secondary Thu, 23 May 2013 19:00:32 GMT McGalliard, Frederick B http://groups.yahoo.com/group/usa-tesla/message/26501 http://groups.yahoo.com/group/usa-tesla/message/26501 You are making it too hard by trying to make it simple. The voltage and current are out of phase, so the power is mostly (and humorously) imaginary. This will,
