CEO and Co-founder, Efficient Power Conversion, USA

Abstract: There are hundreds of millions of people who have experienced the first generation of wireless power transfer technology based on inductive coupling and the Qi format. The promise of convenience has only partially been realized as the limitations of precise positioning and slow charging speeds have become more acute as fast charging of cell phones has become more important to the consumer. Magnetic resonance has long promised to overcome the limitations of Qi with its ability to (a) safely transfer much higher power, (b) enable spatial freedom stemming from large surfaces that can produce uniform magnetic fields, and (c) the ability to have one transmitter couple to a multitude of receivers. In this talk we will discuss the technological, financial, and emotional barriers that need to be broached before widespread consumer adoption of this next generation wireless power technology will gain traction.

Speaker's Bio: Alex Lidow is CEO and co-founder of Efficient Power Conversion Corporation (EPC). Since 1977 Dr. Lidow has been dedicated to making power conversion more efficient upon the belief that this will reduce the harm to our environment and increase the global standard of living. He served as CEO of International Rectifier for 12 years prior to founding EPC in 2007. Dr. Lidow holds many patents in power semiconductor technology, including basic patents in power MOSFETs as well as in GaN transistors and integrated circuits. He has authored numerous peer reviewed publications on related subjects, and co-authored the first textbook on GaN transistors, “GaN Transistors for Efficient Power Conversion”, now in its third edition published by John Wiley and Sons. Dr. Lidow earned his Bachelor of Science from Caltech in 1975, and his PhD from Stanford in 1977.

Safety of RF Wireless Power Transfer Technology

Prof. James C. Lin

Professor Emeritus, Department of Electrical and Computer Engineering, University of Illinois at Chicago, USA

Abstract: Wireless power transfer (WPT) systems are being deployed to provide needed electric power either directly or via battery-charging services using a very wide spectrum. The optimism on WPT technology is clearly driven by the ubiquity of cell phones, laptops, and other mobile communication devices. Aside from not having to plug in the mobile phone or laptop, an fascinating cause for the interest in battery charging through WPT comes from the potential for mobile communication devices to get their electrical power the same way they get their data through harvesting ambient electromagnetic radiation. The dream is a truly wireless mobility scenario with completely tether-free electric power supply for mobile phones, laptops, electric appliances, and various transportation systems. Beyond wireless communication uses, the level of transmitted electromagnetic power required for large-scale or commercial implementation of WPT would be substantial. A key facet of the system design and research effort should include consideration of biological effects and human safety, especially in the RF region of the electromagnetic spectrum. This talk will feature my perspectives on RF safety of WPT technologies.

Wireless Power and Power Beaming

Abstract: Language and nomenclature affect the way we think. In recent years, the taxonomy of wireless power has grown to include technologies and modalities across a wide range. Whether it refers to short-range energy transmission between systems without connectors or long-range delivery of energy over distances far exceeding a meter, there is value in defining the different classifications of wireless power transmission. In this keynote, Dr. Jaffe will give a summary overview of different approaches to one such classification scheme, in which power beaming will be distinguished as a clear subset of wireless power transmission. He will review recent progress for microwave, millimeter-wave, and optical power beaming, and discuss near-term plans and next steps. The discussion will be framed by the contexts of emerging applications and of longer-term visions of future possibilities.

Speaker's Bio: Paul Jaffe is an electronics engineer and researcher with over 25 years of experience at the U.S. Naval Research Laboratory (NRL). He has led or held major roles on dozens of space missions and on breakthrough technology development projects for civilian, defense, and intelligence community sponsors, including SSULI, STEREO, TacSat-1, TacSat-4, ORS, MIS, PRAM, CARINA, RSGS, PTROL, S2FOBs, and LEctenna. He was responsible for electrical system and spacecraft computer hardware development.

To get a Grip on the Earth and Shake it:’ Nikola Tesla’s Scheme for Wireless Power Transmission

Prof. W. Bernard Carlson

Vaughan Professor of Humanities, Department of Engineering and Society, University of Virginia, USA

Abstract: Along with developing a practical AC motor, Nikola Tesla [1856-1943] contributed to electrical engineering by working for fifteen years on a scheme to transmit power wirelessly around the world. Inspired by the experiments of Heinrich Hertz and spurred on by a rivalry with Guglielmo Marconi, Tesla built two broadcasting stations, first in Colorado Springs [1899-1900] and then at Wardenclyffe on Long Island [1901-1905]. At these locations, Tesla pumped energy into the earth’s crust in order to set up a stationary electromagnetic wave at the earth’s resonant frequency. Tesla believed that people would tap into this wave for power and messages by simply grounding a receiver that “would be no bigger than a pocket watch.” In this talk, I will outline the evolution of Tesla’s thinking about wireless power in the 1890s and 1900s as well as his unsuccessful efforts to launch a business around this technology with funding from J.P. Morgan and others. Overall, I will suggest that Tesla was motivated to provide messages and power to millions of people and hence was among the first to recognize that the Information Revolution of the twentieth century would be about empowering individual users.
