Chris,To resonate a 1uF cap at 2MHz, you need a 6.3E-9H primary inductor. That`s awfully small.
(about one inch diameter, single turn) Surge current @ say, 1000V will be 12+kA Di/Dt will be 100kA/uS Do you have a SCR that doesn`t latch at these conditions? Cheers, Finn Hammer Chris Swinson skrev:
John ,Chris, It sounds to me that you're planning to use the SCR to replace the sparkgap. The tank will ring down while the SCR is turned *on*. The SCR willextinguish when the energy rings down sufficiently. If this is what you plan, it's not a new idea. I've used SCR's in this way in Tesla coils, Lou B. has done it, Malcolm W. has done that and probably others too. Terry's SISG coils use the same concept except he used an IGBT which is kept on during the transfer time. The overall concept being that the solid state device is not switched at the RF frequency, but rather at the break-rate frequency. JohnTrue the SCR idea is not a new idea. You are correct in what you say. Though whay should be a new idea is to use 2mhz high Q system and a 1,000uF tank cap all at low voltage... If this has already been done before then I would like to review the specs and data, would save me weeks of time in development! I started this project about 8 months ago now :-(Chris _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
