A three phase IM is fed from a three-phase inverter whose output voltage is represented by a space vector V, = 100e/165° . The DC link voltage Vdc=600V and PWM frequency is 8 kHz. a) Determine which base vectors are needed for generating this voltage. Calculate the time duration of these base vectors c) Draw one period of the PWM switching sequence to generate the expected voltage using symmetric pulsation and both zero vectors and indicate the duration of every switching state in the diagram.
