Conselho Nacional de Desenvolvimento Científico e TecnológicoThis study proposes a modulation strategy based on geometric approach for a hybrid multilevel converter with single dc voltage source. This multilevel converter is composed of a three-phase three-level multilevel converter with neutral-point-clamped (NPC) connected in series with single-phase three-level full-bridge cells. The NPC converter operates at the fundamental frequency of the reference signals, and the switching angle of the switches is calculated to ensure that the fundamental component of the NPC converter output voltage is equal to the fundamental component of the reference voltage of the entire hybrid multilevel converter. Therefore, the full-bridge cells, which opera...
