EE Systems Seminar

Wednesday, October 26, 2016

4:00 p.m. to 5:00 p.m.

Moore B280 - Caltech Campus

Dr. Robert Pilawa-Podgurski

Assistant Professor, Electrical and Computer Engineering at University of Illinois, Urbana-Champaign

Extreme power density and efficiency power converters for grid-interfaced applications - new circuit topologies and controltechniques to leverage wide band-gap semiconductor devices.

ABSTRACT: AC/DC and DC/AC power conversion is critical in a number of emerging applications, ranging from solar photovoltaic systems and battery storage systems to high efficiency data centers and electric vehicle charging. This talk will describe new circuit architectures and control methods that our research group developed for the Google/IEEE $1M Little Box Challenge - an international power electronics design competition with the goal to demonstrate the highest power density 2 kW, 400 VDC to 240 VAC DC/AC inverter with stringent thermal and electrical requirements. I will provide background information on some of the key technical challenges associated with grid-interfaced power converters that are critical for a future sustainable energy infrastructure. I will also provide an overview of two key technical breakthroughs that our group has developed in this space: ultra-high efficiency active line frequency filtering and GaN-based multi-level inverter architectures with record power density and efficiency. Finally, I will highlight some future research areas that we are targeting in the area of electric transportation.
