Hi everybody , this is my first sharing in this forum , I face some problems in my study about the overlap which relates or originates in some semiconductor devices which have a source inductance and an inductive load (highly inductive load) .

I want some informations about the following circuits :

- single-phase half-wave controlled & uncontrolled circuit with comutating diode .
- single-phase bridge circuit .
- fully-controlled single-phase bridge circuit .
- half-controlled single-phase bridge circuit .
- 3-phase half-wave circuit using diodes .
-3-phase half-wave controlled circuit using thyristors .

I need the wave-forms that are related to each case and also the mathematical equations that include ( Vd.c , Vmaan & firing angle gama ).

Thank you for helping me

Most of those topics make effective search terms in Google. Try a bit of research and reading. We do better with specific questions.

You should have a read through the Ebook here. (At the top of every page)

You may also want to download a simulation program. That way you can build the circuit on the screen and see the waveforms themselves.
