In the single-phase half-wave rectifier shown below, assume that the load current

In the single-phase half-wave rectifier shown below, assume that the load current la is constant (load inductance L is very large). (a) Sketch waveforms of the load voltage V, and the thyristor current it for a = 60. (b) Find the average power supplied to the load Pay as a function of the firing angle a. (c) The thyristor has a constant voltage of V-1.2 V across it when it conducts. Find the average power dissipated by the thyristor for a = 90. + Vs (240 V rms) VT i= I R Vo R=20 L (large)
