Abstract
Sinusoidal pulse width modulation (SPWM) control techniques, computer readable mediums, and apparatus are presented for operating a multilevel converter, in which a desired AC node voltage level is determined through comparison of a plurality of carrier signals or values to at least one reference signal or value, and a switching state is selected from a plurality of redundant switching states corresponding to the desired AC node voltage level for generating switching control signals based at least partially on a switched capacitor voltage balancing goal or other control objective.
