Hi all,
Can someone please tell me the basic difference between a Variable Voltage Drive (VVD) and a Variable Frequency Drive (VFD) in terms of industrial applications. Why can't VFD be used for all speed control applications or the likes in general?... i.e., why a requirement of a VVD?
Also, please ennumerate the industrial applications in which a VVD is preferred over a VFD and why.
Thanx & regards,
Shahvir
