摘　　要：为减小逆变器输出电流的谐波含量,本文探讨了中点箝位单相逆变器的工作原理,在三电平中点箝位单相逆变器拓扑结构的研究基础上,提出了一种控制逆变器输出电压为五电平的实现方法,即五电平中点箝位单相逆变器拓扑结构;并基于Matlab/Simulink仿真平台,对基于五电平控制的中点箝位单相逆变器进行了深入研究,仿真结果验证了本文所提控制策略的有效性。In order to reduce the harmonic content of inverter output current,this paper discusses the working principle of a neutral point clamped(NPC)single-phase inverter.Based on the research of topological structure of three-level NPC single-phase inverter,a realization method for controlling the output voltage of the inverter to five-level is proposed,that is,the topological structure of NPC single-phase inverter based on five-level.Based on Matlab/Simulink simulation platform,the NPC single-phase inverter based on five-level control is deeply studied.The simulation results verify the effectiveness of the proposed control strategy in this paper.
