Q. Circuit turn – off time of an SCR is defined as the time :

A
taken by the SCR turn to be off
B
required for the SCR current to become zero
C
for which the SCR is reverse biased to reduce its current below the holding current
D
for which the SCR is reverse biased by the commutation circuit
Solution:

Circuit turn – off time of an SCR is defined as the time during which a reverse voltage is applied across the thyristor during its commutation process.
