A solar cell of 350 V is feeding power to an ac supply of 440 V, 50 Hz through a 3-phase fully controlled bridge converter. A large inductance is connected in the dc circuit to maintain the dc current at 20 A. If the solar cell resistance is 0.5 Ohm ,then each thyristor will be reverse biased for a period of 

(A) 125o (B) 120o (C) 60o (D) 55o
