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 )
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.
