摘要
为在电力电子相关课程讲授过程中引入最新专业知识,对多电平变换器的拓展型仿真实验进行了研究。以模块化多电平变换器(MMC)为例,分析其拓扑电路以及基于载波移相脉宽调制策略的基本原理,基于Matlab/Simulink仿真软件建立了MMC系统的仿真模型,利用仿真结果形象而直观地对比分析了不同控制策略对MMC输出特性的控制效果以及各自的优劣。为帮助学生更好地理解、巩固和拓展相关的最新知识点,激发学习兴趣和创新思维打下良好的基础。
In order to introduce the latest knowledge into the teaching of power electronics course, the extended simulation experiment of multilevel converter is carried out. Taking the modular multilevel converter （MMC） as an example, the simulation model of MMC system is established based on Matlab / Simulink simulation software through the analysis of the circuit topology and basic principle of different control strategies based on carrier phase shift pulse width modulation. The simulation results show the control effect of different control strategies on the output characteristics of MMC visually as well as their advantages and disadvantages. In order to lay a good foundation to help students to understand, consolidate and expand the relevant latest knowledge points better, and to stimulate their interest in learning and innovative thinking.
