thyristors/diodes
(OP)
Hi
How do I test a thyristor/diodes?
Can anybody suggest a maintenance interval/strategy for a thyristor operated device?
I am interested in a generic output waveform expected from a thyristor. Can somebody please explain the concept of the firing angle and how it affects the operation of a thyristor?
Thanks in advance






RE: thyristors/diodes
That's a lot of explanation. I would suggest that you get a book on SCR theory. GE's SCR Handbook ( if it's still published) is excellent. Even an out of date one. Mine is from '63 but, I still find occassion to use it.
A quick explanation. By varying the phase angle at which the SCR conducts, you change the effective voltage.
Good luck

God bless!

Thyristors need no maintenance, but it is very good if you know something about their operation. There are many tutorials available on the web. Do a google search for SCR, thyristor, DC drive and such things. The previous posts have told you some of the fundamentals and the rest is out there.
Good luck
