Abstract

This paper discusses three kinds of triangle carrier PWM strategies (subharmonic PWM, triangular carrier phase shifting PWM, and switch frequency optimal PWM) applied to a cascade multilevel converter (cascade inverters with separated DC sources). The control effects of them are compared through simulation results using Saber simulation software. Some conclusions and suggestion are given.

串级多电平变换器的PWM控制研究

本文讨论了应用于级联多电平变换器(分离直流源级联逆变器)的三种三角形载波PWM策略(次谐波PWM、三角形载波移相PWM和开关频率最优PWM)。利用Saber仿真软件对其控制效果进行了仿真比较。最后给出了一些结论和建议。
