标题： Evolution of Pulse width modulation techniques of modular multilevel converter

摘要： 模块化多电平换流器（MMC）是一种有前景的高压大功率应用转换器技术。 其原因是可以通过每个开关较低的平均开关频率以及无需输出滤波器来实现畸变较小的输出量。 评估了基于模块化多电平换流器脉宽调制的控制方法。 采用多载波PWM技术，如相位放置PWM（PDPWM）、反向相位放置PWM（PODPWM）、交替反向相位放置PWM（APODPWM），并基于负载电压和负载电流输出质量进行了对比研究。 本文介绍了基于半桥子模块拓扑的单相模块化多电平换流器的仿真。 使用MATLAB/Simulink对各种调制技术进行了仿真，并观察了结果。 显示英文摘要

摘要： The modular multilevel converter (MMC) is a promising converter technology for various highvoltage high-power applications. The reason to that is low-distortion output quantities can be achieved with low average switching frequencies per switch and without output filters. Modular multilevel converter pulse width modulation based control approaches are evaluated. The multicarrier PWM techniques such as Phase disposition PWM (PDPWM), Phase opposition disposition PWM (PODPWM), Alternate phase opposition disposition PWM (APODPWM) is employed and a comparative study is done based on the quality of the load voltage and load current output. This paper presents the simulation of single phase modular multilevel converter based on Half-Bridge sub module topology. Simulation has been carried out for various modulation techniques using MATLAB/Simulink and the results are observed.
