1.  less than x% due to an increase in the number of pulses

2.  equal to x%, the same as that of the single phase converter

3.  greater than x% due to changes in the input and output voltages of the converter

4.  difficult to predict as the analysis of converters in not governed by any generalized theory

4
Correct Answer :

greater than x\% due to changes in the input and output voltages of the converter
