With respect to the below given circuit, from ωt = 0 to α,

(a) voltage across all the thyristors is zero

(b) negative voltage appears across T1 and T2

(c) load voltage is Vm/2

(d) voltage across T3 and T4 is zero

I had been asked this question during an interview for a job.

I want to ask this question from Single Phase FW AC-DC-2 in division Converters of Power Electronics

Right option is (d) voltage across T3 and T4 is zero

The explanation is: T1 and T2 are not yet gated, hence they block the forward voltage where as no voltage exists across T3 and T4.
