The three phase 50V full wave AC voltage controller (shown below) is used to control the AC output voltage supplying to a 1002 resistive load. The six Thyristor in the three Triac are turned ON in the sequence 1, 2, 3, 4, 5, and 6 at 60° intervals. Sketch the output voltage appears across Van for a firing angle a -45 Then calculate the r.m.s output voltage, the r.m.s output and supply current, the output power, the apparent power, and supply power factor for the same firing angle. Vo Vs 1-3+sin(2a)]. Solve the question 3-4 with your own hands supply SCR SCR SCR SCR SCR
