A single-phase full-bridge voltage source inverter is operated with SPWM (sinusoidal pulse width modulation).

A single-phase full-bridge voltage source inverter is operated with SPWM (sinusoidal pulse width modulation). The input DC voltage is 100 V. If the amplitude modulation index is 1, the RMS value of the fundamental component of the output voltage is

Right Answer is:
70.7 V

SOLUTION

For Pulse width modulator (PWM) full-bridge rectifier the output voltage is given by

V_{out fundamental} = 0.707 × m × V_dc

Where

Amplitude modulation index = m = 1

Input DC voltage = V_dc= 100 V

V_{out fundamental} = 0.707 × 1 × 100

V_{out fundamental} = 70.7 V
