Next Generation Power Electronic Systems: A Paradigm Shift in Design Philosophy
Presented by Ayan Mallik, University of Maryland

Tuesday, February 26, 2019
10:45–11:45 a.m.
Santa Catalina (SANCA) 151, Polytechnic campus [map] 

This seminar is free and available via Zoom Video Conferencing.


Power electronics has emerged as an enabling technology in the deployment of next generation of systems including transportation systems, motor drives, robotics, renewable energies, smart grids and data centers, among many others. The demand for higher efficiency, enhanced reliability higher power density, specific power and better thermal management poses stringent challenges for the power electronic converters to accommodate. This presentation will put forward some of the emerging research areas, which have been pursued with the emphasis on more-electric-aircrafts (MEA), next-generation onboard chargers for electric vehicles and data center power supplies. A novel approach to replace transformer rectifier units (TRUs) by actively controlled and lightweight Regulated Transformer Rectifier Units (RTRUs) employing the advantages of emerging wide band gap (WBG) semiconductor technology will be presented. In addition, this presentation will focus on an innovative topology to combine an onboard charger and an auxiliary power module with the objective of enhancing the performance, while adding extra functionalities and enhancing the operation efficiency in light and medium loads. Also, a new direction in multi-objective optimization and reliability assessment for power electronic systems will be discussed in this presentation.
