Question 1): (2.5pt) The controlled, three-phase, center-tapped rectifier of Fig. 1 is supplied from a Y-connected three-phase ac source (the RMS of phase voltage U=220V, frequency f=50Hz). The load is a series RLE combination with R=112, E=100V and the inductor is large enough to consider the load current to be continuous and ripple-free. The delay angle (a) is a/3, [rad]. id uvitvi uvat va uvat v3 1 IV1 iV2 4103 + 11 ud tou (a) Sketch the output voltage and the load current waveforms (ud, id) (1pt) (b) Determine the average value of output voltage (Ud) (0.5pt) (c) Sketch the input phase current waveform (ii) (0.5pt) (d) Determine the power factor (Ud.Id/S) (0.5pt) E 13 Fig. 1
