What is delay angle or what is firing angle of phase controlled rectifier?

Description : What is delay angle or what is firing angle of phase controlled rectifier?

Last Answer : The delay angle is the angle at which thyristors are triggered after zero crossing. After zero crossing of supply voltage, one pair of thyristors is forward biased. After delay angle(α) these SCRs are triggered.
