Request for Information (RFI) on Public Feedback on AMMTO Wide Bandgap Power Electronics Strategic Framework

The U.S. Department of Energy (DOE) issued a Request for Information (RFI) to gather public feedback on the draft Advanced Materials and Manufacturing Technologies Office (AMMTO) Wide Bandgap Power Electronics Strategic Framework. This initiative aims to support the evolution of wide bandgap (WBG) power electronics, which are essential for advancing the capabilities of U.S. critical infrastructure, as traditional silicon technologies struggle to meet performance demands. The RFI seeks input from stakeholders to refine the framework, potentially leading to a Notice of Funding Opportunity (NOFO) in the future. Key areas of inquiry include gaps and challenges in power electronics technology, emerging trends, cross-industry connections, regulatory barriers, educational workforce development needs, and specific innovations required for materials and manufacturing. Respondents are encouraged to identify promising technologies and barriers to commercial viability and suggest strategies for fostering collaboration in research and innovation. The RFI emphasizes that no funding or project support will be provided as a result of responses. Input will inform the DOE's program strategies, highlighting the importance of public engagement in shaping the future of power electronics in the context of U.S. energy resilience and industrial competitiveness. Responses are due by April 11, 2025, and must follow specific submission guidelines.

The U.S. Department of Energy (DOE) has developed a Wide Bandgap Power Electronics Strategic Framework aimed at enhancing energy independence and securing the power grid through technological innovations in wide bandgap (WBG) and ultra-wide bandgap (UWBG) materials. These materials offer superior efficiency and performance compared to traditional silicon-based systems, making them essential for modernizing the power electronics (PE) sector. The framework outlines four key focus areas: applications to various infrastructures (grid, transportation, digital, and industrial), the necessary materials and devices, passive components and packaging, and supportive non-technical aspects such as workforce development. The strategic goals include increasing system power density, enabling higher voltage operations for grid applications, integrating materials advancements, and fostering collaboration across the PE ecosystem. Critical challenges identified include the limitations of existing silicon technologies and the need for educational initiatives to prepare a skilled workforce. The document emphasizes the importance of collaboration between industry, academia, and government to overcome barriers and drive the adoption of WBG technologies, ultimately to meet future energy demands and enhance the reliability of the electrical grid. Through coordinated efforts and roadmaps, the framework seeks to establish a competitive U.S. manufacturing sector in power electronics.
