Abstract
A device, method, and non-transitory computer readable medium that determines a multilevel inverter circuitry comprising Nsource DC voltage sources and at least 2Nsource+5 controlled switching devices. The number of output voltage levels and the maximum output voltage of the multilevel inverter circuitry can be variable and depend on a trade-off among voltage rating of switches, variety of DC sources, and control strategy. A hybrid modulation scheme is employed to reduce the total harmonic distortions.
