| Abstract: | Cascade and neutral-point-clamped(NPC) converter have become increasingly popular in recent years due to their practicability.This paper presents an improved hybrid cascade multilevel converter that is derived from these two topologies.The proposed converter is the series-connection of a diode-clamp converter and several H-bridge converters with the equal dc bus voltage.According to this topology,a hybrid modulation method which incorporates square-wave synthesis in conjunction with unipolar triangle carrie... |
