Choose the correct statement

(a) M-2 type connection requires SCRs with higher PIV as compared to those in a B-2 type

(b) M-2 type connection requires SCRs with lower PIV as compared to those in a  B-2 type

(c) The average output voltage in M-2 type is more than that obtained from a B-2 type configuration of the same rating

(d) The average output voltage in M-2 type is less than that obtained from a B-2 type configuration of the same rating

I got this question in a job interview.

This interesting question is from Single Phase FW AC-DC-3 in chapter Converters of Power Electronics

Right option is (a) M-2 type connection requires SCRs with higher PIV as compared to those in a B-2 type

The explanation: The PIV of diodes in M-2 is 2Vm, whereas that in B-2 type of connection is Vm.
