摘要
近数年来,我国在PWM变频器的生产与应用方面发展很快,从而提出了PWM变频器的输入输出特性以及驱动特性如何测量的问题。本文以SY_1-552型PWM变频器的特性测量为例,讨论了有关问题,可供有关方面参考。
In recent years, with the rapid development of the production and application of PWM frequency convertor, questions have been raised regarding ways to measure the input-output and driving characteristics of PWM frequency convertor.By citing the example of the SY_1-552 PWM frequency convertor developed by ourselves, the article discusses the characteristics measuring problems, which are for relative reference.
