Novel Power Electronic Systems Enabled by Wide Band-Gap Semiconductors
September 13, 2016
Washington, D.C. 

ARPA-E hosted a workshop entitled “Novel Power Electronic Systems Enabled by Wide Band-Gap Semiconductors” on September 13, 2016 in the Washington, D.C. area. The workshop convened leading experts in power electronics, power systems, circuit design, wide bandgap materials, semiconductor devices, packaging and module design, and end use applications to identify innovative research paths forward for the development of disruptive advanced circuit topologies that lead to higher efficiency, more reliable, reduced size and weight, and lower cost devices and/or system architectures.  Participants lended their expertise to help ARPA-E determine appropriate and compelling experiments and metrics that promote innovation and sufficient evaluation of advanced circuit topologies.

Request for Information: Novel Power Electronic Systems Enabled by Wide-Bandgap Semiconductors (Responses due 10/17/16)

ARPA-E is interested in advanced circuit topologies that enable higher efficiency, more reliable, smaller form factor and weight, and lower cost devices and system architectures across a range of applications including, but not limited to: 

Power Supplies
 Lighting and LED drivers 
 Solar Inverters / Power Conditioners
 Data Centers and Information Technology
 High-Performance Computing Centers
 Electric Motor Driven Systems
 Automotive (Electric and Hybrid Electric Vehicles)
 Wind-Electric Systems
 Utility Applications and UPS
 High/Medium Voltage Transmission/Distribution
 Rail and Ship Propulsion
 Grid Efficiency

Areas of interest and targeted outcomes include: 

 Identification of appropriate evaluation methods and metrics across application areas of interest
 Identification of any other/new application areas that could be significantly improved through advanced circuit topologies and that would have a significant energy impact.
 Identification of the technical challenges that need to be overcome through advanced circuit design for wide bandgap devices.
