摘　　要：多电平逆变电路泛指其输出量具有多个电平的电路。由于在高压大容量场合,与传统的两电平逆变器相比较,它具有高电平、谐波含量低等很多优势,因而发展十分迅速。文中首先以二极管箝位式三电平逆变器为例,介绍了三电平逆变器的基本原理,然后简要分析了三角载波层叠PWM技术,最后在MATLAB/Simulink平台环境进行仿真分析,实现了对三电平逆变器的仿真,具有一定可行性。The circuit of multi-level inverter circuit refers to the output with multiple levels. Because of the high voltage and large capacity,compared with the traditional two level inverter,it has many advantages,such as high level,low harmonic content,and so on. In this paper,the diode clamped three level inverter as an example,this paper introduces the basic principle of three level inverter,then briefly analyzes the triangular carrier PWM technology,finally the simulation analysis on the MATLAB/Simulink platform,and the simulation of three level inverter,which shows the feasibility.
