Project 1

Assumptions-

1-Input supply=415 volt line rms, 50Hz.

2-Here, for both two cases i have taken highly inductive load of 50A in simulation equivalent to controlled current source of 50A.

FOR UNCONTROLLED RECTIFIER(Simulation file is attched in browse section)

FOR CONTROLLED RECTIFIER(Simulation file is attched in browse section)

As we can see from the comparision of three phase uncontrolled with controlled rectifier the power factor at input side of converters is more compare in uncontrolled rectifier.
