3. The circuit shown in Fig. Q3 is a single-phase half-wave controlled rectifier operating from a 240V, 50Hz supply, Given the load resistor 2002: (a) Plot the output voltage, output current and voltage across the SCR if the firing angle (a) is at 30°. (6 marks) (b) Calculate the firing angle (a) if the average output voltage is regulated at 90% of the maximum possible average output voltage. (9 marks) (C) If the load resistor is decreased to 106, calculate the firing angle (a) required to maintain its average output current.
