中文摘要: 不对称级联型多电平变频器拓扑结构各单元直流母线的电压不尽相同,采用混合控制策略,可以用较少的功率器件输出更多的电平数,达到更好的输出性能.引入最大延伸定理,为不对称级联型多电平变频器各单元选取电压比值提供理论依据,同时给出了一种改进型不对称级联型多电平变频器拓扑结构.
Abstract:The DC bus voltage value in different cells of asymmetry cascaded multilevel inverter is different.If the mixed control strategy is applied, the number of output levels are big and the output performance is better.The maximal distention principle is introduced as the theory reference of voltage value in different cells.At the same time, an improved topology is proposed
