A 240V, 50 HZ voltage supply is feeding power to a 1002 resistor through a controlled half-wave rectifier operating at a firing angle of 120° as shown in Figure 1. a. Sketch the supply voltage, the load voltage and the voltage across the thyristor (show all relevant magnitudes and angles). b. Calculate the average output voltage and current. c. Find the peak reverse and peak forward voltages of the thyristor. d. Calculate the form factor and ripple factor of the current. y V T R www 20 E Figure 1 A 240V, 50 HZ voltage supply is feeding power to a 1002 resistor through a controlled half-wave rectifier operating at a firing angle of 120° as shown in Figure 1. a.
