The full-wave, phase-controlled rectifier of Figure is supplying a highly inductive load such that the load current can be assumed to be purely dc, as represented by the current source Idc in the figure. The source voltage is a sinusoid, Vs (t) = V0 sin wt. As shown in Figure, SCRs T1 and T3 are triggered together at delay angle ?d (0 a. For ?d = ?/4:

(i) Sketch the load voltage v`s (t).

(ii) Calculate the average (dc) value Vdc of V's (t).

(iii) Calculate the time-averaged power supplied to the load.

b. Repeat part (a) for ?d = 3?/4.
