Q1: A single phase half wave controlled rectifier circuit has a free wheeling diode. The load is a combination of R and L. The firing angle is a. The period of conduction of SCR and free wheeling diode respectively are

A
a < ωt < p and p < ωt < (2p + a)

B
a < ωt < p and p < ωt < 2p

C
a < ωt < p and p < ωt < (2p - a)

ANS:A -

a < ωt < p and p < ωt < (2p + a)

SCR conducts from a to p and free wheeling diode from p to (2p + a).
