Q#1 Phase Controlled Converter GATE EE 1995 MSQ +2 marks -0 marks

The single phase half controlled ac to dc bridge converter of figure supplies a 10 Ohm resistor in series with a 100V back emf load. The firing angle of the thyristors is set to 60°

 

(i) Find the average current through the resistor

(ii) What will be the new average current through the resistor, if a very large inductor is connected in series with the load?

I(avg)=7.406 A

New average current I = 4.352 A

I(avg)=3.703 A

New average current I = 3.504 A
