3. A three-phase voltage-fed inverter uses SVM method to supply an isolated neutral wye-connected machine load. Assume the following parameters: DC link voltage V = 300 V Carrier frequency f = 10 kHz Fundamental frequency f = 10 Hz Fundamental voltage V = 100 V (rms) (a)Draw the power circuit. (b)Assume that in a certain sampling period, the command vector lies at a lagging angle of 150, i.e., between the inverter vectors V4(011) and V5(001). Calculate the pulse width and gap for each phase (in us) for symmetrical PWM pulses. Show clearly the on and off devices during the sampling period T=1/fs.
