Question

Problem 2: (40 points) Consider a three phase dc-ac converter employing space vector PWM using the conventional sequence (0127 in Sector 1). The sampling interval Ts is 100 μs and the dc link voltage is 400 V. (a) Calculate T1, T2 and Tz for the following two cases REF (in per unit)- 0.7530 and (2) REF(in per unit)- 0.75280 (b) Draw the waveforms of VaN, Vh and VeN for the above two cases over two sampling intervals (c) Draw the waveforms of Vab' Vhe n Vea for the above cases over two sampling intervals
