An inductive load consists of a resistance and an inductive reactance connected in series. The circuit is excited by a full-wave ac/dc SCR converter. The ac voltage (input to the converter) is 120 V (rms), and the circuit resistance is 5 ?. At a triggering angle of 30o, the load current is continuous. Calculate the following:
a. Average voltage across the load
b. Average load current
c. rms voltage across the load
Since the current through the load is continuous, SCR1 will turn off only when
SCR2 is turned on at ? +? . Hence, the conduction period for each SCR is from
? ? ? to + .
a. To find the average load voltage:
b. Average load current:
c. Since the current is continuous,
