Question

Calculate the average value of the current through the thyristor in case of 1-Φ Full wave bridge rectifier if the value of the load current is 42 A.

(a) 21 A

(b) 12 A

(c) 14 A

(d) 16 A

I had been asked this question in an online quiz.

I need to ask this question from Solid State Controlled Drives topic in portion Introduction to Solid State Controlled Drives of Electric Drives

Answer 1

Correct answer is (a) 21 A

For explanation: The average value of the current through the thyristor in case of 1-∅ full wave bridge rectifier is Io÷2=21 A. Each thyristor conducts for 180°.
