AA chopper circuit in the figure, 400 V (rms)
Control the power of an ohmic load from a 50 Hz source.
Since the load resistance is 20 Q and a = 30 °,
a) The effective voltage, current and power of the load,
b) Input power factor,
c) Apparent, active and reactive powers drawn from the network,
winw w
d) Minimum blocking voltage of thyristor,
e) Average value of each thyristor current,
f) The required firing angle for the power transferred to the load to be 80% of the maximum
power,
calculate.
Note: The equation reached for obtaining the trigger angle can be solved by the heuristic
solution method.
For this, the solution is reached by giving values to the angle.
