A single-phase full converter with B-2 type of connection has a continuous load current waveform. The thyristor pairs T3, T4 is triggered at ωt =

(a) 0

(b) α

(c) π+α

(d) π-α

I had been asked this question by my school principal while I was bunking the class.

I'm obligated to ask this question of Single Phase FW AC-DC-2 in chapter Converters of Power Electronics

Right answer is (c) π+α

The best explanation: First, at α T1-T2 conduct, then after π+α the next pair is excited i.e. T3-T4 and likewise.
