A three-phase, 12-pulse rectifier is fed from a transformer with a nominal voltage rating of
400k(V)/(220)kV. If the primary voltage is
450kVand the effective turns ratio
Tis 0.4 , determine the dc output voltage when the ignition delay angle
\alpha is
22\deg and the commutation angle
\mu is
20\deg under the following additional conditions: (a) Calculate the dc output voltage. Assume no ignition delay and no overlap. [3] (b) Calculate the dc output voltage assuming there is only ignition delay, but there is no overlap. [2] (c) Calculate the dc output voltage considering both ignition delay and overlap.
