当加上非线性负载如调速电动机驱动器时,会影响正弦电源。电压波形畸变变成非正弦波。
When nonlinear loads, such as adjustable speed motor drives, affect a sinusoidal power source, the voltage waveform is distorted and becomes nonsinusoidal.
讨论了变频电源输入电压的非正弦对测功电机的性能影响,提出改善不利影响的措施。
In this paper, the functional influence of input voltage non-sine of Varible-frequency voltage source on Electric Power Dynamometer motor discussed. and methods of improving them were also given.
