A 3-phase 6-pulse diode rectifier is shown below with phase sequence R-Y-B. The negative group of diodes (D4, D5, D6) conduct in sequence (from ωt = 0°)

A 3-phase 6-pulse diode rectifier is shown below with phase sequence R-Y-B. The negative group of diodes (D4, D5, D6) conduct in sequence (from ωt = 0°) Correct Answer D5-D6-D4

The conduction sequence always depends on the phase sequence, which diode is conducting will depend upon which phase voltage is active at that moment.
