Variable speed AC drive technology has been applied to a wide range of fields, from industrial applications to consumer electronics, and so has become an indispensable technology in modern society.
In order to expand such technology into new areas and achieve further levels of sophistication, it is important to investigate new trends in the application of transport mechanism AC drives (represented by automobiles). It is also important to investigate the latest technology trends in industrial drives, railroad-vehicle drives, other general drives, etc.
This technical report is a summary of the results of an investigation conducted by The Institute of Electrical Engineers of Japan's (IEEJ) Investigating R&D Committee on Frontier of Variable Speed AC Drive Technology regarding the latest trends in variable speed AC drives. The investigation focused on various technologies that contribute to new areas of application for the variable speed AC drive, and the data presented in this report is classified based on the area of application and its corresponding technology.
