In the single-phase half-controlled rectifier shown below, the source voltage is 240

In the single-phase half-controlled rectifier shown below, the source voltage is 240 V rms. The load: R= 1002, L is very large. Assume that the load current io-la is constant. (a) Sketch the load voltage waveform (vo) (use a = 90) and show that its average is given by V (1+cos ) V = de (b) Sketch the source current i, for a = 90 and find (i) the fundamental amplitude of is. (ii) the rms value of is. Zi, ZD + R Vo
