That's close. A full explanation is here: http://www.allaboutcircuits.com/vol_3/chpt_7/5.htmlHello Everybody! I am new to this forum. I want to ask you why a thyristor is called a rectifier. Is it because it acts as a Diode to some extent- it has an anode and a cathode. ?
Thanks in advance for your help!!
A full wave bridge rectifier is what you described. A rectifier can be be a single diode, or any other of many types of components that can be used to rectify. Even a mosfet can be used as a rectifier. a DC generator is a mechanical rectifier.a rectifier is 4 diodes used to turn AC into DC.
Ah... I guess our experiences with SCR/thyristors is a little different. I'm not sure what you've seen, but what I've seen is that they're used mostly for AC power control, not for protection. Actually I'm not sure how you would even use one for protection. Wouldn't seem like a good idea to me, as their common failure mode is shorted.A Thyristor is a protection device almost like a fuse/breaker.
Google crowbar circuit. It is common to use thyristors in such a circuit. However I do not think this circuit are very common to day. It was more a circuit used in CRT TVsA full wave bridge rectifier is what you described. A rectifier can be be a single diode, or any other of many types of components that can be used to rectify.

Yeah I was just trying to keep it simple, I don't know a lot about SCRs except the crowbar circuit and that's because we spent an entire class discussing a crowbar circuit lol.A full wave bridge rectifier is what you described.

I think you're describing a thermistor.basically the thryistor goes across the AC lines, and in the event it gets too hot it shorts to blow the main fuse, also works for surges......but like I said, I don't understand why it's used that way.
I think you're describing a thermistor.
EDIT: never mind, I googled the crowbar circuit and I see what you're talking about.
Absolutely. I was wondering about why the question is, when the name itself is very clear. Only after your answer I realized the expansion is probably not so popular!Some early abbreviations (acronyms);
GR = germanium rectifier
SR = silicon rectifier (diode)
SCR = silicon controlled rectifier (diode that can be controlled)
