engineering recuitment UPCL AE (E&M) 2021 Mock Test Power Electronics and Drives Inverters Pulse Width Modulated Inverters
In the sinusoidal pulse-width modulation scheme, if the zero of the triangular wave coincides with the zero of the reference sinusoidal, then the number of pulses per half cycle is
1
\(\frac{{{f_c}}}{{2f}}\)
2
\(\frac{{{f_c}}}{{2f}} + 1\)
3
\(\frac{{2{f_c}}}{f}\)
4
\(\frac{{{f_c}}}{{2f}} - 1\)
