多级联型准Z源逆变器的研究
|
摘要
提出一种多级联型准Z源逆变器拓扑。与传统的准Z源逆变器相比,该新型拓扑的升压倍数随着级联数的增大而增大,应用场合更广。主要研究了一个开关周期的工作过程,通过分析该新型电路拓扑的工作原理,推导出各部分电压关系,并用MATLAB/SIMULINK进行软件仿真,证明了理论分析的正确性。以二级联型准Z源逆变器为例,通过工作原理分析、参数设计、电路仿真和实验验证,论证了二级联准Z源逆变器构造方法的可行性,通过归纳可证明多级联型拓扑构造的合理性。
A multilevel quasi-Z-source inverter topology is proposed in this paper. Compared with the quasi-Z-source inverter,the voltage gain of the multilevel quasi-Z-source inverter increases with the number of cascade,and the application is more extensive. In this paper,the working process of a switching period is studied. By analyzing the working principle of the new circuit topology,the voltage relationship was obtained,and the MATLAB/SIMULINK simulation was carried out to verify the correctness of the theoretical analysis. And through the analysis of working principle,parameter design,circuit simulation and experimental verification,the feasibility of the cascaded quasi-Z-source inverter was proved. The rationality of multilevel topological structure is also proved by induction.
