Multilevel inverters, including the flying-capacitor topology require more complex control due to the additional flexibility offered by the multiple output voltage levels. One such control method is based on the conventional sinusoidal pulse width modulation (SPWM) scheme and uses multiple triangular carriers. There are a number of SPWM variants that achieve the desired inverter control. This p...
