Upcoming Webinar: Design Automation for Power Electronics

 Register Here

Abstract – Recent trends in power electronics are driving the need to revisit design tools and capabilities. Wide bandgap technologies have been demonstrated to hold great promise for achieving higher efficiencies, increased volumetric density, and provide system level cost benefits relating to thermal management. However, the faster switching devices and circuits tend to generate more EMI that can disrupt surrounding components, not to mention adversely impacting their own controls to such a degree that failures can be induced.

To address the design of wide bandgap based power electronic systems, electronic design automation tools and methods need to be revised. This webinar will describe many of these problems, the current status and trends being pursued, and stimulate the audience’s thinking on where they might contribute from an R&D perspective. A recent workshop entitled Design Automation for Power Electronics held just prior to ECCE in September 2018 will be reviewed. For the industry practitioner looking to apply design methods, tools and techniques, the review of the current status will be valuable and give them an indication of things to be watching for in the near future, or approaches they could adopt to address their issues. Topics to be covered include semiconductor device modeling, power module design, cabinet level design, and multi-objective optimization.


Alan Mantooth 2017 croppedH. Alan Mantooth received the B.S. and M.S. degrees in electrical engineering from the University of Arkansas in 1985 and 1986, respectively, and the Ph.D. degree from the Georgia Institute of Technology in 1990. He then joined Analogy, a startup company in Oregon, where he focused on semiconductor device modeling and the research and development of modeling tools and techniques. In 1998, he joined the faculty of the Department of Electrical Engineering at the University of Arkansas, Fayetteville, where he currently holds the rank of Distinguished Professor. His research interests now involve analog and mixed-signal IC design & CAD, semiconductor device modeling, power electronics, and power electronic packaging. Dr. Mantooth helped establish the National Center for Reliable Electric Power Transmission (NCREPT) at the UA in 2005. Professor Mantooth serves as the Executive Director for NCREPT as well as two of its centers of excellence: the NSF Industry/University Cooperative Research Center on GRid-connected Advanced Power Electronic Systems (GRAPES) and the Cybersecurity Center on Secure, Evolvable Energy Delivery Systems (SEEDS) funded by the U.S. Department of Energy. In 2015, he also helped to establish the University of Arkansas’ first NSF Engineering Research Center entitled Power Optimization for Electro-Thermal Systems (POETS) that will focus on high power density systems for transportation applications. Dr. Mantooth holds the 21st Century Research Leadership Chair in Engineering. He served as President for the IEEE Power Electronics Society in 2017-18. Dr. Mantooth is a Fellow of IEEE, a member of Tau Beta Pi and Eta Kappa Nu, and registered professional engineer in Arkansas.


Miroslav Vasic

Miroslav Vasić was born in Serbia in 1981. He received the B.S. degree from the School of Electrical Engineering, University of Belgrade, Belgrade, Serbia, in 2005. Since then he has been working at Centro de Electrónica Industrial at ETSII (UPM) where he received his M.S. in 2007 and his Ph.D. degree in 2010. He has been working as assistant professor at UPM since 2015.

His research interest includes application of power converters and their optimization. In the recent years great part of his research activities has been related to the research of new semiconductor devices based on GaN and their impact on power electronics.

Miroslav Vasić has published more than 70 peer-reviewed technical papers at conferences and in IEEE journals. In 2012 he received the Semikron Innovation Award for the teamwork on “RF Power Amplifier with Increased Efficiency and Bandwidth.” In 2015 he received a medal from Spanish Royal Academy of Engineering as a recognition of his research trajectory and in 2016 he received UPM Research Projection Award for the best young researcher at Universidad Politécnica de Madrid.

Miroslav actively serves as a reviewer in several IEEE journals such as IEEE Transactions on Power Electronic and IEEE Transactions on Industrial Electronics and as an Associated Editor in IEEE Journal of Emerging and Selected Topics in Power Electronics and IEEE Transactions on Vehicular Technology.

Han Peng
Abstract – Gallium Nitride and Silicon Carbide are two representative materials for the third generation wide bandgap semiconductor. Gallium Nitride power transistors have higher electron mobility than SiC, making them superior devices for high frequency and efficient switching. The lateral HEMT device structure is also a more suitable topology for power integration together with driver and control blocks to achieve a ultra-high power density module and system. This presentation will discuss an accurate and comprehensive evaluation of GaN switching characteristics. The effects of gate driver topologies, gate resistors and deadtime will be explored. Several different applications of high frequency GaN based power conversion will be illustrated.
