There are many pulse systems differ by changing firing angles between the set itself and also between the two sets(rectifier+inverter) but i think that the most useful practical way is "seperate control" which depends on sending pulses to one set and removing pulses from the other sequentially....
I need help concerning PSR and PSI cause all that i know is the chart symbols for each of them so i need the real practical circuit used in such cases.
where VA,VB,Vc are 120 phase-shifted of each other.
