摘　　要：阐述了级联型多电平高压变频器的工作原理,介绍了其仿真建模过程,仿真结果表明该级联型多电平高压变频器谐波污染小,输入功率因数高,输出波形好,不必采用输入谐波滤波器和功率因数补偿装置。对高压变频器的开发和研究有一定的参考价值。The basic principle of the cascaded multi-level high voltage inverter is introduced, the process of simulating and model constructing are recommended. The results of simulation show that the cascaded multi-1 evel convertor has little harmonic pollution,high input power factor and good output wave , there is no need to adopt the input harmonic filter and power factor compensation apparatus. It has great value for the development and research of high voltage inverter.
