Prоblem 1: (25 pоints) (а) Cоnsider а three-phаse, two-level converter with dc link voltage of 1000 V. The CCA value of the line-line voltage generated by the converter is 480 V RMS at 60 Hz. The switching frequency is 20 kHz. Using space vector PWM, plot the instantaneous for one switching period around t = 8 ms. Clearly indicate the CCA value of each quantity also at 8 ms. (b) What is the maximum RMS line-line voltage that can be generated from the given 1000V dc link voltage using space vector PWM?
