Hello everyone .. I'm new member in this forum and I hope to be welcomed here..
I have a final yera project which is speed control for DC motor by varying the firing angle of thyristor.

my motor output voltage is 100v at least.
the thing I have read a lot of thyristor controlling part, but a lot of theory drove me crazy..
my real problem is when I see the symbol circuit in books, it juz contain of Ac supply,thyristor and the motor..

I really need to know how to start the designing, what components to include and why must be included (why is it every time I see a circuit, it contains of a lot of components) and how to control the firing angle of the thyristor. (sorry but my practical principles are very weak)
( there is a lot of information I need to know and ur help is really appreciated )

thanx a lot

Re your PM.

You are a final year student and should know this stuff. It is not our job to get you through your final years. In fact, I would feel liable should you kill someone through your lack of knowledge. Revisit my link and read lots and then you might be suitably qualified to call yourself an engineer.

Mike.
