Question 5

a) Draw the circuit of a Three-phase bridge inverter using a Y-connected load and explain its operation using 180 degree conduction clearly showing the gating sequence and the corresponding output line voltages for each phase. (10)

b) For the Y-connected load determine the line to neutral voltages for the three modes of operations. Draw the equivalent circuits for each mode and then draw the phase voltage waveforms for the 180-degree conduction. (7)
