Speech Title: Meeting the Challenges of Embedded Power Electronics in Tomorrow’s Sustainable World

Abstract: Power electronics engineers are facing the challenge of finding more effective techniques for embedding power electronics in an ever-expanding constellation of consumer, residential, industrial, and transportation equipment. Many of the most appealing candidates for embedded power electronics require power levels that are many orders of magnitude higher than our hand-held devices, and they live in environments that are far more hostile in terms of their thermal, vibrational, and corrosive operating conditions. Despite these daunting challenges, incredible progress has already been made during the past 70 years, and extraordinary new developments in wide-bandgap switches, materials, and manufacturing processes are beckoning us to push well beyond the limits of today’s embedded power electronics technology. By looking both backward and forward in time, this presentation will issue a call to all power electronics engineers and our professional colleagues in adjacent fields to engage in this exciting but daunting multi-disciplinary quest to more completely fulfill the destiny of embedded power electronics. We can only succeed by working together, and future generations will thank us for our efforts.

Speech Title: Recent Development in IPM Synchronous Machines for Traction and other Emerging Applications

Abstract: The interior permanent-magnet synchronous machines have now become the mainstay of electric vehicles up to a few hundred kilowatts capacity. The wide constant-power speed range, high efficiency and compact size are the reasons for its wide adoption in the traction industry. The availability, cost and supply issues of the PM materials notwithstanding. This keynote traces the developments over the recent past that led to this and discusses future developments of the IPM motor and its controls that are in the horizon. One of the emerging applications of compact and hence light-weight motors will be in the future aviation industry with vertical take-off aircrafts and drones for personal and commercial transport. These applications are expected to employ multitudes of high-speed machines far beyond the calls of land-based electric vehicles. Another emerging application is for compressors in the air-conditioning industry, especially in data-storage centers, where high speed of operation increases the efficiency of compressors. The trend towards reduced usage of PM materials in machines, with elimination of PM materials in rotor excited machines will also be described.

Speech Title: Advances in Design and Control for Linear Induction Machines and Drives

Abstract: Starting from a brief structural description of single-sided linear induction machines (LIMs), their main applications will be exposed with specific reference to transportation (such as linear metro, light railway, MAGLEV), launchers, actuators for industry, etc. As a first step, the main differences between rotating and linear induction motors will be highlighted, focusing on the aspects end effects in details. Design criteria of LIMs will be specifically discussed, emphasizing the main differences with the classic rotating induction motor design, caused by end effects, large air-gaps, half-filled slots, high leakage inductances, etc. Afterwards, in order to improve the working efficiency, it will share advancements in the accurate modelling, loss minimization control strategy, multi-objective optimization technique, etc., for LIMs and drives. Researchers and engineers from electrical, mechanical and information fields may find this speech very useful when dealing with transportation motor and drive related design, control, system integration, which can be extended to other industrial applications.
