Question

Output voltage of an inverter is controlled by multiple pulse modulation technique. If the peak value of reference voltage is 4 V and peak value of carrier voltage is 6 V. Then the total pulse width in each half cycle is

Answer 1

$V_r=4V$

$V_c=6V$

Total pulse width = 2d

$\frac{2d}{N}=(1-\frac{V_r}{V_c})\frac{\pi }{N}$
(Where N is number of pulses per half cycle)

$2d=(1-\frac{V_r}{V_c})\pi$

$2d=(1-\frac{4}{6}){180}^0={60}^0$
