The San Francisco Bay Area chapter of the IEEE Power Electronics Society (IEEE SFBAC-PELS) is interested in the development of power electronics technology. This technology encompasses the effective use of electronic components, the application of circuit theory and design techniques, and the development of analytical tools toward efficient electronic conversion, control, and conditioning of electric power.

About the talk:
Today's society is seeing a rapid transition from fossil-fuel power sources to an electric grid powered from renewable energy. Likewise, electrification is making significant in-roads in the transportation sector, owing to the increased performance, reduced operating costs, and environmental benefits from electric drive systems. In both areas, power electronics is used for efficient conversion of electric energy and is a key enabling technology.
In this talk I will present our recently developed techniques for drastically improving the fundamental power density and efficiency of power electronics through a new class of hybrid switched-capacitor power converters. An example 2 kW solar photovoltaic inverter prototype from the Google/IEEE Little Box Challenge will be presented to illustrate the achievable performance improvements over conventional techniques, yielding the highest power density (216 W/in^3) published to date by any group. A second example application - electric aircrafts - will demonstrate how lightweight power electronics can enable an entirely new class of low-emission, low-noise airplanes. Designs principles and hardware results from an 18 kW/kg motor drive will be provided.

About the Speaker:
Robert Pilawa-Podgurski received dual B.S. degrees in physics, electrical engineering and computer science in 2005, the M.Eng. degree in electrical engineering and computer science in 2007, and the Ph.D. degree in electrical engineering in 2012, all from the Massachusetts Institute of Technology.
He is currently an Assistant Professor in the Electrical and Computer Engineering Department at the University of Illinois, Urbana-Champaign, and is affiliated with the Power and Energy Systems group. His research interests include renewable energy applications, electric transportation, CMOS power management, and advanced control of power converters. Dr. Pilawa-Podgurski received the Google Faculty Research Award in 2013, and the 2014 Richard M. Bass Outstanding Young Power Electronics Engineer Award of the IEEE Power Electronics Society, given annually to one individual under age 35 for outstanding contributions to the field of power electronics. In 2015, he received the Air Force Office of Scientific Research Young Investigator Award, and in 2016 the UIUC Dean's Award for Excellence in Research. He is most proud of his numerous teaching distinctions based on student evaluations. He is an associate editor of IEEE Transactions on Power Electronics, and IEEE Journal of Emerging and Selected Topics in Power Electronics, and has co-authored six IEEE prize papers in the last four years.

We look forward to having you join us.

June 29, 2017: Webinar: Wide Band Gap Circuit Optimisation and Performance Comparison, by Edward Shelton and Dr. Patrick Palmer.

Register Here!

Abstract: The presentation will start by exploring the significant benefits that can come from using GaN power switching devices in hard-switched PWM applications. It will then be explained how these benefits can be fully realised with a power circuit, gate-drive and PCB layout that are all optimised for fast switching. The performance of such an optimised circuit can only be successfully tested and varified using high performance non-intrusive measurement and instrumentation systems, such as the embedded measurement circuits that will be presented by the authors. Further to this, the circuit design for a linear current-source gate-drive will be presented and compared to a conventional resistive gate drive. Consideration will be given to reliable operation, improved efficiency and reduced EMI.
The goal of this presentation is to demonstrate how to achieve practical, efficient and reliable operation of GaN devices in high-frequency high-power switching circuits.
