| 摘 要： | 以多单元串联型逆变器拓扑结构为基础,提出了一种多电平逆变器通用组合拓扑结构的构成原则,对多电平逆变器拓扑结构的研究进行了统一.根据该通用拓扑结构所提供的自由度,构造出了几种新型的组合拓扑结构.同时,基于传统的应用于多电平逆变器的多载波SPWM调制策略,提出了对应于组合拓扑结构的组合调制策略.仿真结果验证了组合拓扑结构及组合调制策略的有效性,为多电平逆变器组合拓扑结构的实际应用奠定了基础.

| Abstract: | Based on multi-module-cascaded inverter topology, a universal hybrid multilevel inverter topology is introduced in this paper and the research of multilevel inverter structure is unified. According to the free degree of this universal structure, several new hybrid topologies are constructed. At the same time, based on conventional modulation strategies-multi-carrier SPWM applied on multilevel inverter, hybrid modulation strategies are introduced corresponding to hybrid structure. The simulation results proved that the validity of hybrid structure and corresponding modulation strategies, it lays the foundation of practical application on hybrid multilevel inverter structure. |
