Correct Answer : Option (C) : 1200
Explanation : Mainly, there are two types of 3 phase rectifiers: A half-wave rectifier and a full-wave rectifier. Many industries work on 3 phase power supply instead of a single phase. In three-phase half-wave rectifiers, each diode conducts for a duration of 120 0 because the cycle will be repeated itself, and each thyristor conducts for 1200 duration when the firing angle is less than 300.
