Rectify!!

Its 1.30 am. I just emerged out of my books. I have studied a lot by my standards. But I don't think it's going to be enough. I'll have to revise everything tomorrow and also cover the bits I've left(which is a lot) for later. Studies are a pain in the butt, especially when you have to figure out stuff like the output voltage and current waveforms of a three phase to single phase cycloconverter along with a lot of other stuff. Whew!! It would have been a lot easier if the circuit diagrams of the cycloconverters were somewhat different from those of the phase controlled rectifiers or the ac voltage controllers. But nooooooooooooooooo, they all have to have minor modifications like having a freewheeling diode in one circuit but not in the other because it helps in smoothening the final output. Or something like that. I have no clue about anything.

I don't even think what I've just written makes any sense. Well I hope the examiner doesn't read my answers as closely otherwise I'll be studying this shit again next year too. If there is a God, He will prove his existence by having me pass this subject comfortably enough to avoid any chances of a phase inversion which leads to the rectification of the date of passing on my degree.
