Advanced Techniques in Commercial AC Drives
IFAC Proceedings Volumes, 1992Abstract AC drive is now widely applied in commercial adjustable speed drives as a completely established system. Due to the inherent advantages of ac drive, now it not only invades the territory of dc drive, but also creates many new applications which have hitherto never been considered.

The analog control systems were a unique way for implementation in AC drives control for many years. The implementation of microprocessors in the AC drives control has begun in the speed and position loops. The slow speed (position) change allows implementation of 8 or 16 bit microprocessors.

Improving the efficiency of AC-drives
2013 Brazilian Power Electronics Conference, 2013New standards for power losses measurement for variable speed drives are presented. The power losses of typical variable speed drives are analyzed and future alternatives to increase their efficiency investigated. Solutions with Silicon (Si) technology in Three-Level topology or Silicon Carbide (SiC) switches in Two-Level circuit are possibilities to ...

AC drives in the metals industry
Conference Record of the 2002 IEEE Industry Applications Conference. 37th IAS Annual Meeting (Cat. No.02CH37344), 2003The use of alternating current (AC) drives in the metals industry has greatly increased in the last 15 years. This increase appears to be the result of increasing features of drives, more reliable motors and electronics, smaller cost efficient packages, and end user education on applying AC drives.

Application Considerations for AC Drives
IEEE Transactions on Industry Applications, 1983General application considerations for ac variable-frequency drives are discussed. A review of induction motor characteristics and adjustable frequency controller fundamentals is presented as a background for applying the drives. In addition, a brief review of the types of controllers available is provided.

AC drive with particular reference to traction drives
APSCOM-97. International Conference on Advances in Power System Control, Operation and Management, 1997New developments in the design of high speed electric trains are discussed, with reference to the AC drive system. The three level converter-inverter system applying advanced IGBTs, which is implemented in the latest Shinkansen train sets operating in eastern Japan between Tokyo and Nagano, is described.

Proceedings of 5th International Conference on Power Electronics and Variable-Speed Drives, 1994
In variable-speed AC or DC drives, improved responses can be obtained by using fuzzy logic control. The paper discusses the application of fuzzy logic to variable-speed drives and gives a general overview of the structure of fuzzy controllers and various aspects of fuzzy-control. A new fuzzified controller is also introduced.

Abstract This chapter describes a simple gain scheduling robust controller whose parameters are continuously changed by fuzzy logic such that the controller makes the system respond quickly if the error e is large (SIN is large) and vice versa in order to obtain a robust controller which is insensitive to both plant noise and ...

The speed of an AC motor depends on the speed of the rotating magnetic field, which is proportional to the frequency of the AC supply. Speed control is therefore possible with a power electronic controller which can generate a variable frequency. The majority of AC variable-speed drive systems use a DC/AC inverter to generate the required variable ...
