Carrier based PWM scheme for a three-level diode-clamped five-phase voltage source inverter ensuring capacitor voltage balancing

A carrier-based modulation scheme for a three-level diode-clamped five-phase voltage source inverter is presented. This technique employs the generation of three average modulation signals for each inverter leg. These signals are compared with the same high frequency triangular carrier signal to produce the composite switching functions for each respective… (More)
