A Virtual-Vector Pulsewidth Modulation for the Four-Level Diode-Clamped DC-AC Converter

Several pulsewidth modulation (PWM) strategies have been proposed for the three-level three-phase diode-clamped dc-ac converter. Among them, the nearest-three virtual-space-vector PWM guarantees the dc-link capacitor voltage balance under any operating condition, provided that the addition of the th...
