Consider a three-phase thyristor-based AC-DC converter supplying a “superconductive inductance” of 10 H and 200 A. The grid voltage is 400VLL/60Hz. A) What is the shortest time to fully charge the Inductor, from “zero energy condition?” What value of firing angle of the thyristors (α) should be used in this case? B) When the inductor is fully charged, what value of α should be used to keep it at “stand-by”? How much reactive power does the AC-DC converter absorb from...
