MSQ
+2 marks
-0 marks
A d.c. motor driven from a fully controlled 3 phase converter shown in figure, draws a d.c. current of 100A with negligible ripple.
(a) Sketch the a.c. line current for one cycle
(b) Determine the 3rd and 5th harmonic components of the line current as a percentage of the fundamental current
Third harmonic current as a percentage of Fundamental current = 0%
Fifth harmonic current as a percentage of Fundamental current =20%
Third harmonic current as a percentage of Fundamental current = 10%
