True, I know I brought up the topic some years ago about using power
SCR/IGBT in place of spark gaps, though the prices were too high, I think
Terry invested in SISG but was many before also but on lower power levels.
One of the reason I am working on my high Q design is that it only needs to
operate up to 100V, and that will equal a 2KW power supply. Uses a huge SCR,
but there world is flooded with low voltage types and can pick them up on
ebay for next to nothing.
DRSSTC seem great, was tempted to build one, but decided "its always been
done" kind of thing now, but for sure a great solid state design. I am going
for a single SCR high Q design, a LOT of work, though in itself is nothing
new, but a real pain to design.. Hopefully once the "beta version" is proven
some more people will jump in with thier own variations...
