In days of yore (say, 10 years ago).. the peak power in a SG TC (say, discharging several tens of joules at 30kV) was higher than you'd get in a SSTC (because the pass devices can't take the peak current). Consider a primary with a 0.035 uF cap charged to 30kV discharging into a 80 uH primary (fres around 95-100 kHz).. The peak current is about 630 A. back when, this would be a challenge to handle with FETs (or a vacuum tube). I suppose today, one can get IGBTs that can handle that sort of peak current.The power gap between SGTC and SSTC has been gone since the invention of the DRSSTC. For a while there was quite a price gap between DRSSTC and SGTC, but lately that seems to be narrowing.
when considering retail prices for components, or eBay/Surplus prices? Those popular CM600 bricks run about $400-500 each retail..
As to the peak currents, in general the peak currents you find in a SGTC of a given size are considerably lower than those you find in a DRSSTC of a similar size. There are many DRSSTCs that running tank currents well in excess of 1kA these days. -Phillip Slawinski _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxx http://www.pupman.com/mailman/listinfo/tesla
