WIRELESS POWER TRANSFER
Imperial College London, UK
Delivery of power wirelessly to portable devices is an alternative method to energy harvesting sustain operation beyond periods that can be attained with a battery. In this talk I will cover the basics of inductive power transfer, including modelling the link, transmit and receive circuits and safety. We will look at the feasibility and limits for powering sensor type devices using this technology and compare it to the capabilities of an energy harvesting based solution. The technology will be illustrated with several demonstrators.
Paul D. Mitcheson (SeniorMember, IEEE) received the M.Eng. degree in electrical and electronic engineering and the Ph.D. degree in micropower motion based energy harvesting for wireless sensor networks from Imperial College London, London, U.K., in 2001 and 2005, respectively. He is currently a Professor in Electrical Energy Conversion with the Control and Power Research Group, Electrical and Electronic Engineering Department, Imperial College London. His research interests include energy harvesting, power electronics, and wireless power transfer to provide power to applications in circumstances where batteries and cables are not suitable. His research has been supported by the European Commission, Engineering and Physical Sciences Research Council, and several companies. Dr. Mitcheson is a Fellow of the Higher Education Academy and is on the Executive Committee of the U.K. Power Electronics Centre. He was the General Co-Chair of IEEE Wireless Power Week in 2019 in London, U.K and is Vice Chair (conferences) of IEEE PELS TC-9, Wireless Power.
