A novel carrier interleaved PWM method for four-level nested neutral-point-clamped inverters

The four-level nested neutral-point-clamped (4L-NNPC) inverter is a competitive topology among the various medium-voltage multilevel converters, and its main issue is flying-capacitor voltage unbalance. In this article, a novel carrier-interleaved pulse width modulation (CIPWM) method that satisfies...
