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
Options
A. a < ?t < p and p < ?t < (2p + a)
B. a < ?t < p and p < ?t < 2p
C. a < ?t < (p + a) and (p + a) < ?t < 2p
D. a < ?t < p and p < ?t < (2p - a)
Correct Answer
a < ?t < p and p < ?t < (2p + a)
Explanation
SCR conducts from a to p and free wheeling diode from p to (2p + a).
