Ds, Ozgic USTUN January 18™ 2021 POWER ELECTRONIC CIRCUITS Fall 2020 Midterm Exam - 2 Question - 4 A single phase full-bridge inverter is supplying a series RL load (R=3O, L=0.05H) from a 200V DC source. The full square-wave output waveform period is 1Oms. The controlled switches are IGBTs. Assume the circuit is ideal. a. Sketch the scaled load current for first two periods from starting by calculating. (Assuming 4,=0 at #0) b. For steady state operation find the maximum and minimum values of load current. Calculate the IGBT conduction time. Calculate the diode conduction time. Sketch the scaled voltage across the load inductance. Calculate the RMS value of load current Calculate the mean value of the source current. @ moan | : = 200¥ 4 a 3) T,<-8RA
