Q1/ A Two-Source Multilevel Inverter For the two-source multilevel inverter of Fig. 8-9 with V = 100 V: (a) Determine the Fourier coefficients through n = 9 and the modulation index for a₁ = 20° and a₁ = 40°. (b) Determine α, and a such that the third harmonic (n = 3) is eliminated and M, = 0.8. Q/2 A Five-Source Multilevel Inverter Determine the delay angles required for a five-source cascade multilevel converter that will eliminate harmonics 5, 7, 11, and 13 and will have a modulation index M, = 0.8.
