The 3-phase modulating waveforms
and
, used in sinusoidal PWM in a Voltage Source Inverter (VSI) are
where
is the fundamental frequency. The modulating waveforms are compared with a 10 kHz triangular carrier whose magnitude varies between +1 and −1. The VSI has a DC link voltage of 600 V and feeds a star connected motor. The per phase fundamental RMS motor voltage, in volts, is closest toYour answerChoose one option.
