Hello I have recently been covering firing angles in rectifiers at uni. I didn't really understand it in the lecture, and the tutorial questions/one to one with the lecturer didn't help either. It would also seem that the internet isn't of much help either from a quick Google search and as we now have a coursework question on this subject all the relevant textbooks are out in the library. So I was wondering if anyone has any good links to resources on rectifiers, in particular on calculating the firing angle. From what I understand it "can't" be calculated?
