Question
A single phase half wave converter is used to charge a battery of 50 V. The thyristor is continuously fired by dc signal. Input voltage is v = V_m sin ?t. The thyristor will conduct
Options
A. from 0 to 180�
B. when v > 50 V
C. from 0 to 90�
D. When v < 50 V

Correct Answer

when v > 50 V

Explanation

Thyristor can conduct only when it is forward biased. This occurs only when v > 50 V.
