| 摘 要： | 通过仿真研究，指出在应用折角调制方法和移缺口方法作为大功率变频器输出电压转入方波工况的策略时，必须注意转换点的选取，并提出了相应的选取方法。对这两种方法以转矩脉动量为标准做了对比，指出折角调制方法是一种更好的方法。

| Abstract: | As the result of simulation, it is pointed out that the converting point must be carefully chosen when corner folding modulation method or intermediate pulse displacement method is used to convert the output voltage waveform of high power frequency converter into square waveform. Comparison of torque pulse quantities between the two method leads to the conclusion that the corner folding modulation is a better choice. |
