Analysis of voltage waveform of a single phase bridge converter shows that it cont ains x% of 6t h harmonic. The 6th harmonic content of the voltage waveform of a 3-phase bridge converter would be

A. less than x% due to an increase in the number of pulses
B. equal to x%, the same as that of the singlephase converter
C. greater than x% due to changes in the input and output voltages of the converter
D. difficult to predict as the analysis of converters is not governed by any generalised theory
