The half-bridge inverter of Fig. P1.1 supplies an R-L load with R= 8 12 and L = 40 mH, Vs = 408 V, and frequency f = 400 Hz. Assume that idi(t) Q1 and Q1 are each turned on during 50% of each half cycle. Vs D, , (a) Determine the maximum forward voltage that a transistor must + Vo withstand. (b) Determine the (i) maximum, and (ii) minimum inductor currents. D2 (c) Determine the rms value of i.(t). io(t) Q2 (d) Determine the power delivered to the load. (e) Sketch and label (include values) the waveforms current v. and the current VD2 using the same time axis. Indicate the time Fig. P1.1 intervals when each switch component (Q1, D1, Q2, D2) is conducting. (f) Sketch and label (include values) the waveforms current i, and the current idi using the same time axis. Indicate the time intervals when each switch component (Q1, D1, Q2, D2) is conducting. + The half-bridge inverter of Fig. P1.1 supplies an R-L load with R= 8 12 and L = 40 mH, Vs = 408 V, and frequency f = 400 Hz.
