Example 1.1, Bridge rectifier. LCC

Описание: Consider a bridge-connected rectifier (AC to DC), and it is fed by using a step-down transformer, 230 k/120 kV, from the VL= 230 kV AC supply.
Determine the DC voltage output (Vd) when the commutation angle is Gamma = 15° and the delay angle (alpha) is:
(a) alpha = 0°;
(b) alpha = 30°;
(c) alpha = 60°.
