一种具有更高直流母线利用率的T型与H桥级联九电平逆变器拓扑

This article introduces a hybrid nine-level inverter topology with extended dc-bus utilization for operation at over modulation range without the presence of lower order harmonics (predominantly fifth and seventh) when compared to conventional two-level and multilevel inverter with hexagonal voltage space vector structure. The proposed inverter is a cascade of a five-level T-type unit and an H-bri...
