Home » Power Electronics » Power electronics miscellaneous » Question

In a 3-phase rectifier circuit, thyristor number 1, 2 and 3 are connected respectively to R, Y, and B phases of the star connected transformer secondary. When the current is being commutated from thyristor No. 1 to No. 2 the effect of the transformer leakage and the a.c. system inductance will be such that it will—

1. Prolong the conduction in No. 1 at the scheduled time but delay the turn ON of No. 2 correspondingly
2. Stop the conduction in No. 1 at the scheduled time but delay the turn-ON of No. 2
3. Produce conduction in both No. 1 and No. 2 in parallel for an overlapping period through a transient
4. Double the voltage o/p through a commutation transient
