It's been a little while since I did any in-depth study of power
electronics, but I seem to remember reading about GTO (gate turn-off)
thyristors - which is are SCRs that can be returned to a non-conducting
state by applying a negative trigger pulse to the gate.  Has anyone else
heard of these?  I think I still have the book that mentions them; I'll
see if I can find it.
