变频器的英文译名是VFD(Variable-frequency Drive),是应用变频技术与微电子技术,通过改变电机工作电源频率方式来控制交流电动机的电力控制设备。 1、什么是变频器? 变频器是利用电力半导体器件的通断作用将工频电源变换为另一频率的电能控制装置,能实现对交流异步电机的软起动、变频调速、提高运转精度、改变功率因数、过...
Danfoss变频器采用交—直—交电路结构，其控制方式经历了几个重要阶段。首先，U/f=C的正弦脉宽调制（SPWM）控制以其结构简单、成本低的优势，能满足一般传动的平滑调速需求，广泛应用于工业领域。然而，SPWM在低频时存在输出电压低导致转矩受定子电阻影响、动态性能不理想等问题。为改善这些问题，矢量控制...
