电力驱动器效率的研究

Looking at Electric Drive Efficiency

变频驱动器(VFD)在众多负载和转速各异的应用实例中,表现出了令人印象深刻的节能作用。除了能节省动力和能量外,变频驱动器的效率还有另一个受人关注的原因,与电动机类似,驱动器在部分负载的工作状态下,其效率会出现大幅的下降。

Variable-frequency drives(VFDs) provide dramatic energy savings in myriad applications with varying loads and speeds.While power and energy savings are key benefits,VFD efficiency is also of interest because drives can experience significant efficiency losses at partial load operation-much like electric motors.
