Nowadays more and more universities and colleges have taken the cultivation of pragmatic students as the core of guiding teaching ideology which focuses the task of teaching students practical skills to meet the demand of society for better employment. This trend has to be carried out by the delicate design of teaching schemes andgreat change of teaching method and students achievement evaluation system.

阐述了模块化多电平换流器的基本工作原理和损耗数值计算方法,应用PLECS仿真软件针对半桥子模块结构,分析了载波移相调制下不同均压、环流抑制方式下的子模块损耗特性,认为在不影响换流器工作状态的前提下,使用能量均衡法均压以及使用三相解耦二次谐波环流抑制算法进行环流抑制时,各子模块损耗分布一致性更高,整体损耗率更低。通过比较,还发现不同工况下的子模块损耗一致性接近。最后,对比了载波移相调制与最近电平控制调制方式下的损耗一致性,认为载波移相调制下子模块损耗一致性更高。
