Innovative application technologies of AC motor drive systems

Abstract

This paper deals with the innovative application technologies on variable speed AC motor drive systems. These application technologies are categorized on the basis of the advantages of the AC variable speed motor drive systems, such as downsizing, pACkaging with high density, energy savings, better availability and maintenancebility, higher controllability of the torque and speed, load leveling. Various component technologies such as the power conversion technology, control technology, and motor technology are also mentioned along with their related application technologies. Future perspectives of the AC drive application technologies are discussed in the conclusion of the paper.
