Comments in response to this RFI must be submitted to PowerAmerica
Background and Rationale:
The U.S Department of Energy (DoE) launched the PowerAmerica Institute under the initiative of National Network of Manufacturing Institutes (NNMI) to accelerate adoption of wide bandgap power devices. The Institute is being managed by North Carolina State University.
PowerAmerica is accelerating the adoption of advanced semiconductor components made with silicon carbide and gallium nitride into a wide range of products and systems. Backed by $70 million from the U.S. Department of Energy over five years, PowerAmerica is working to make these wide bandgap semiconductor technologies cost-competitive with silicon-based power electronics and reduce their perceived risk in industrial applications.
PowerAmerica brings many of the world's leading wide bandgap semiconductor manufacturers and end-users together with experts from top research universities and government agencies to accomplish its objectives. Through participation in the PowerAmerica ecosystem, industry members grow their business by accelerated wide bandgap product introduction to market, and University members gain by engaging in collaborative projects with industry.
In addition to soliciting information from its numerous members that span all areas of wide bandgap semiconductor device and power electronic systems, PowerAmerica strongly encourages responses from industry/universities with technical activities highly relevant to the PowerAmerica mission who have not yet joined the PowerAmerica ecosystem. In the RFI guidelines and topics, PowerAmerica has outlined objectives formulated through internal planning and through informal discussions with stakeholders.
