Hi, I am building a coilgun and heard that SCRs were good for triggering them, i got a few 800V 16A (200A peak) SCRs from my local electronics store and rigged one up in essentially this circuit (apologies that it is in paint):
I am only charging the caps to about 100v for testing but the SCRs keep breaking, I am rather new to SCRs so do I need a resistor in the gate connection? Do I need a bigger SCR? Is there some other switching device you know of that I can use?
I don't know the inductance of my coil but here are some SCR stats:
Igt - 80ma
dV/dt - 100 V/us
Thanks for any help you can give.
