The single-phase thyristor rectifier shown in the figure below is supplied with an AC voltage of 230 Vrms 50Hz and delivers a direct current of Id=50A to the output. The commutation inductance L, has a value of 0.5 mH. For a firing angle of 30°: ULS Lig Id vd a) Draw the input voltage (us (t)), the output voltage (out (t)) and the input current (ice (t)). Identify the components as conductor (the four thyristors) in different time intervals. All drawings must be clear, including numerical values on both axes b) If the firing winding increases (30° <a <90°) and the load current is kept constant and unchanged, what will happen to the commutation interval? Will it decrease, increase or remain indefinite? Justify your answer.
