Unformatted text preview: EE610 HW#11 2011 - Not to turn in 1) Using the voltage waveform shown in Figure 13.3-2, use a Fourier Series to derive the funda- mental component of the phase voltage . 2) Given a single-phase H-bridge inverter. The output voltage is shown. The output load is induc- tive with mH, Hz, A. Plot from 0 to . Label the devices conducting over the entire waveform. 3) Given a 3-phase inverter operating under sine-triangle modulation. V. The inverter is sourcing a wye-connnected 3-phase resistive load with . The phase-a duty cycle under is (b and c have the same amplitude but diplaced by 120 degrees). a) Plot the fundamental component of the phase-a voltage you would expect to see out of the inverter on the following plot. v as L 1 = f c 1000 = i out ( 29 2 = i out 2 c 2 v out 2-- 3 2------ 16 16 i out c V dc 200 = r load 1 = d a 50 c 4-- cos = 4) For the circuit shown below, the switching signal and a-phase current are shown on Page 2. switching signal and a-phase current are shown on Page 2....
