DESCRIPTION:Abstract: Numerous trends are driving the need for advances in 
 electrical power conversion technologies\, including rapid deployment of r
 enewables in the electric power grid and electrification of the transporta
 tion sector. Soft magnetics technologies play a critical role as an enable
 r for state-of-art power electronics conversion topologies and systems abl
 e to fully exploit the latest advances in wide bandgap (WBG) and ultrawide
  bandgap (UWBG) semiconductor-based switching devices. Current commercial 
 soft magnetic materials and manufacturing solutions are not optimized for 
 these new application requirements. Amorphous and nanocrystalline soft mag
 netic alloys have emerged as the premier solution for many WBG-based power
  electronics converter applications\, including medium frequency transform
 ers and inductors\, as a result of increased saturation flux densities rel
 ative to ferrites and reduced eddy current losses compared to electrical s
 teels. Historically\, brittle mechanical properties of nanocrystalline all
 oys have limited their application in WBG power electronics conversion. In
  case of future UWBG power electronics\, alternative soft magnetic materia
 ls systems and manufacturing pathways are required for the unprecedented c
 ombinations of power\, voltage\, and switching frequencies. This presentat
 ion will provide an overview of needs and examples of future engineering d
 esign pathways being pursued. Specifically\, we will discuss (1) emerging 
 nanocrystalline alloys with improved magnetic properties and enhanced duct
 ility combined with advanced manufacturing methods for WBG power electroni
 cs and (2) new ideas in ferrite based soft magnetic materials for future U
 WBG power electronics. An overview of some relevant commercialization effo
 rts as it relates to amorphous and nanocrystalline soft magnetics technolo
 gy will also be discussed. Broader needs for workforce development in adva
 nced magnetic materials and devices for power applications will also be ad
 dressed.\n\nCo-sponsored by: Virginia Commonwealth University\, Department
