A purely inductive, balanced, Y-connected load having an inductance L per phase, is fed by the three-phase half-bridge inverter shown below in Figure Q5. The inverter is operated in the square-wave mode (meaning that the pole voltages are square waves) with a frequency fs. A purely inductive, balanced, Y-connected load having an inductance L per phase, is fed biy the three-phase half-bridge inverter shown below in Figure Q5. The inverter is operated in the square-wave mode (meaning that the pole...
