摘　　要：介绍了级联多电平中压变频器工作原理,给出了总体设计。阐述了硬件体系结构,又用软件工程方法进行数据字典编写、软件模块划分与调度、数据变量定义,降低了难度,提高了系统可维护性,最后开发出产品。经过实验测试,达到要求。Principle of multilevel middle voltage inverters was introduced and total system was designed, It gave architecture of hard- ware, method of compiling of data dictionary and the allocation and dispatching of program module, the definition of variability act was done by software engineering method. So the complexity simplified and maintainability enhanced, in the end succeed in development of the man- ufactured product, after the experiment,it is to be found that the product meets the requirements.

关 键 词：多电平中压变频器 软件模块 分配PWM脉宽 中断服务
