Q1:

If Vdc1 is the dc output voltage in half wave controlled rectifier circuit feeding resistive load and Vdc2 is the dc output voltage in full wave controlled rectifier circuit (M - 2 connection) feeding resistive load, then

A Vdc1 = 0.5 Vdc2 for all values of firing angle

B Vdc1 = Vdc2 for all values of firing angle

C Vdc1 ≤ 0.5 Vdc2 for all values of firing angle

D Vdc1 ≥ 0.5 Vdc2 for all values of firing angle

ANS:A - Vdc1 = 0.5 Vdc2 for all values of firing angle

and Vdc = (1 + cos a).
