Q1:

A single phase fully controlled bridge rectifier is fed by a source having inductance. The output voltage during overlap period is

A Vm

B 0.5 Vm

C zero

D 0.5 Vm - voltage drop across inductance

ANS:C - zero

During the period of overlap all the four thyristors conduct and load is effectively short-circuited. Output voltage is zero.
