Q1:

In a 3 phase full wave regulator feeding a star connected resistance load the input voltage is 400 V line to line. The firing angle is 160°. The line to line output voltage would be

A 400 V

B about 100 V

C about 20 V

D zero

ANS:D - zero

In a three-phase full wave regulator, output voltage is zero if a ≥ 150°.
