Questions Regarding Funding Opportunity Announcements

Please contact the ARPA-E-CO@hq.doe.gov email address for questions regarding Funding Opportunity Announcements. Upon the issuance of a FOA, only the Contracting Officer may communicate with Applicants. ARPA-E personnel and our support contractors are prohibited from communicating (in writing or otherwise) with Applicants regarding the FOA. This “quiet period” remains in effect until ARPA-E’s public announcement of its project selections.

ARPA-E will not pre-assess an Applicant’s proposal. Prospective Applicants must review the technical requirements of the FOA and independently determine whether their proposed concept warrants a submission.

DE-FOA-0001609: Request for Information (RFI) on Novel Power Electronic Systems Enabled by Wide-Bandgap Semiconductors

ARPA-E seeks input from the power electronics, electrical engineering, and circuit design communities regarding the development of next-generation advanced circuit topologies for use in power electronics systems that facilitate higher efficiency, more reliable, reduced size and weight, and lower cost devices and/or system architectures. Consistent with the agency’s mission, ARPA-E is seeking clearly disruptive, novel technologies, early in the R&D cycle, and not integration strategies for existing technologies.

With advanced circuit topologies, it is possible to envision realizing efficiency gains both directly, by inherently more efficient designs, and indirectly, by facilitating higher levels of adoption for fundamentally higher performing materials. ARPA-E desires input from a broad range of disciplines and fields, including, but not limited to: power electronics, electrical engineering, circuit design, wide-bandgap materials, semiconductor devices, packaging and module design, and others. This includes input from the developers and end-users of such technologies, such as power supplies, LED drivers, data centers, automotive (Electric and Hybrid Electric Vehicles), high-performance computing centers, solar inverters/power conditioners, electric motor driven systems, wind-electric systems, high/medium voltage transmission/distribution, rail/ship propulsion, and emerging new applications not yet categorized. ARPA-E is particularly interested in how next-generation advanced circuit topologies will help to realize the promise of higher efficiency systems.

Please carefully review the REQUEST FOR INFORMATION GUIDELINES below, and note in particular: the information you provide will be used by ARPA-E solely for program planning, without attribution. THIS IS A REQUEST FOR INFORMATION ONLY. THIS NOTICE DOES NOT CONSTITUTE A FUNDING OPPORTUNITY ANNOUNCEMENT (FOA). NO FOA EXISTS AT THIS TIME. Respondents shall not include any information in their response to this RFI that might be considered proprietary or confidential.

Background:

Power electronics are an integral part of many energy systems, including but not limited to power supplies, LED drivers, data centers, automotive, solar inverters, and electric motor drives. By 2030, an estimated 80% of all U.S. electricity is expected to flow through power electronics[1]. Because of this high potential impact, ARPA-E has invested significantly in programs to develop power electronics technologies[2],[3],[4]. These previous efforts have focused primarily on material and device development where advanced wide-bandgap semiconductor materials, such as silicon carbide and/or gallium nitride, would be substituted for silicon, but mostly without focused consideration and redesign of the circuit topology. Direct replacement of Si devices by wide-bandgap semiconductor devices offers limited improvements in power electronic performance metrics. Thus, there is now an opportunity to build on the successes from earlier programs and aim for both higher performance, as well as increased market penetration of these highly promising technologies.

Given the capabilities of emerging wide-bandgap materials and devices, ARPA-E believes there are new opportunities for innovations in power electronics such as converter circuit topologies and architectures, resonant and soft switching, control techniques, integration and packaging, and system architectures. These innovations can support ARPA-E’s mission by leading to higher efficiency power conversion in two different ways: (1) directly, through realization of design that are more efficient and (2) indirectly, by enabling inherently higher efficiency wide-bandgap materials. Recent advances have demonstrated high performance wide-bandgap semiconductor devices, but they have not yet achieved high rates of adoption because power circuits have not been designed that exploit their inherent advantages. Additionally, there are concerns about the cost and reliability of wide-bandgap semiconductor devices. New circuit topologies could be designed to fully extract the potential of wide-bandgap semiconductor devices while addressing the cost and reliability concerns.

ARPA-E believes that the timing is right to leverage recent progress in electronic materials and devices to fully realize their benefits. There are numerous precedents for advances in device technology to require new approaches at the circuit and system level for significant proliferation of the technology. For example, recent programs in compound semiconductors have driven progress in envelope tracking circuits for reducing power (which extends lifetime), as well as performance improvements via heterogeneous integration with other device technologies[5]. Basic materials and device developments (e.g., low-k dielectrics, silicon-on-insulator wafers, Cu interconnect) are typically slow to be adopted often due to reliability concerns and can take 5-10 years until circuit and product teams learn how to make use of the new technology reliably in their designs. This is currently happening with recent progress in 3D memory technology, with designers learning to leverage the new capability[6],[7]. Solar inverters provide another example, with circuit designs incorporating distributed inverters throughout solar cells, the overall reliability and performance of the system are improved compared to having one larger inverter farther away from the solar panels. This guidance from the recent history of progress in advanced electronics has generated ARPA-E’s interest in a potential effort in novel power electronic systems enabled by wide-bandgap semiconductors to continue to advance the exciting power electronics technologies developed in previous R&D projects.

ARPA-E is thus seeking input from the broad research and development community with regard to developing advanced circuit topologies and systems; in particular, circuits that incorporate advanced wide-bandgap materials that are inherently more efficient, such as SiC or GaN. In addition, we would like to understand all barriers to adoption, whether technical or market-based and any ideas on which might be solved through innovative circuit design. Such insights that leverage the application and adoption of these advanced circuit topologies to well-defined end-use applications are strongly encouraged.

Purpose and Need for Information:

The purpose of this RFI is solely to solicit input for ARPA-E consideration to inform the possible formulation of future programs intended to help create transformative converter circuit topologies that enable innovative higher efficiency power electronics systems. ARPA-E will not provide funding or compensation for any information submitted in response to this RFI, and ARPA-E may use information submitted to this RFI on a non-attribution basis. This RFI provides the broad research community with an opportunity to contribute views and opinions regarding the advanced circuit topologies development path, energy use and adoption consideration in relevant end-use applications. Based on the input provided in response to this RFI and other considerations, ARPA-E may decide to issue a Funding Opportunity Announcement (FOA). If a FOA is published, it will be issued under a new FOA number. No FOA exists at this time. ARPA-E reserves the right to not issue a FOA in this area.
